Build a Double Decker Litter Box: Make Use of Vertical Space

Double Decker Litter Boxes Save Floor Space

If you’re a proud cat parent to more than one furry feline, you know the struggle of keeping multiple litter boxes in your home. With limited floor space, those boxes can quickly take over your bathroom or laundry room. But what if you could stack those litter boxes and make use of vertical real estate? Enter the double decker litter box – the innovative solution for multi-cat households.

Going Up: Taking Litter Boxes to New Heights

A double decker litter box is essentially two litter boxes stacked on top of each other, connected by a ramp or stairs. This design allows you to have two litter boxes side-by-side while taking up half the floor space. And your cats will love having multiple levels to climb, play, and do their business. It’s a win-win! But you may be wondering – how do you build one of these vertical litter box structures?

The good news is that while store-bought double decker litter boxes can be pricey, you can easily DIY one at home for a fraction of the cost. All you need are some basic supplies from your local hardware store. The construction is straightforward enough for even novice DIY-ers to accomplish in an afternoon.

Building Materials: Picking Sturdy Walls and Floors

When selecting materials for your double decker litter box, you’ll want to choose options that are sturdy, easy to clean, and impervious to any errant sprays of urine. Many cat owners opt for finished plywood, unfinished wood boards, or wire storage cubes.

Plywood offers an smooth, easily wiped surface. Unfinished wood like pine can be sanded, primed, and painted for a more polished look. Storage cubes provide a quick and adjustable wire frame option. Consider your felines’ habits and aesthetic preferences when making material choices.

Litter Pans: Containing the Mess

For the actual litter trays, sifting pans are highly recommended. They allow urine and waste to fall through while keeping litter locked in place. This helps contain the mess and odor in each box. You’ll want pans that are large enough for an adult cat to comfortably turn around in.

Make sure to get two pans – one for each level. Attach them securely to the frame using zip ties or hardware. Non-slip shelf liner under the pans can help prevent shifting. And consider adding subtle identification cues like color or patterns to help cats distinguish between levels.

Ramps and Stairs: All Aboard!

To allow easy movement between the upper and lower levels, integrate a gently sloped ramp or set of stairs. The ramp can be made from a wide board covered in carpet, or you can opt for a set of simple wooden steps. Place the ramp/stairs in an easy to climb position.

Cats generally prefer ramps over perpendicular ladders. Make sure the slope is not too steep. Consider adding a lip or guard rails to prevent accidental slips. High traction carpet will give paws grip.

Privacy Panels: Cozy Retreats

Some cats desire privacy when doing their business. To create a cozy, secluded place for timid felines, install panels around the litter boxes. You can use flexible PVC sheets, pegboard, or wood. Cut panels to fully enclose the front and sides, leaving an entrance hole.

These hideaways allow shy kitties to feel protected. But make sure panels don’t block your ability to fully access the litter trays for cleaning. And include adequate ventilation holes to prevent odor buildup inside.

Air Filters: Reducing Smelly Situations

Speaking of odor control, placing air filters near the litter boxes can help minimize smelly situations. Activated charcoal filters are affordable options that absorb odors. You can also install small computer fans to keep air circulating.

Position the air filters strategically to filter the nearby air. Use unscented varieties to avoid overwhelming your cats’ sensitive noses. Proper litter box maintenance is still required, but air filters offer backup support.

Toys and Perches: Play Opportunities

Adding toys and perches lets your cats reap the full benefits of their new vertical playground. Attach or hang interactive toys from the upper level to create enticing play spaces. Perches or ledges allow kitties to observe their domain from on high.

Make sure toys don’t dangle over the litter pans. And don’t place perches right above the boxes either, to avoid any unwanted “raining down” incidents. But do get creative with tunnels, swings, and lookout spots to keep your cats enriched and engaged.

Mats and Trays: Tidying Up Tumbles

Build a Double Decker Litter Box: Make Use of Vertical Space

Despite your best ramp efforts, spills and tumbles may still occur. Place absorbent mats or litter catching trays beneath the upper litter box to catch any fallen debris. You can use commercial mats, plastic trays, or even sheets of tarp or cardboard.

Having this protective lining helps keep your floors clean if litter gets kicked over the edge. It also protects your cats from injury and gives you peace of mind.

With the right materials, tools, and a little DIY spirit, you can build an incredible double decker litter box for your cats. Your furry friends will be thrilled with their new multi-level hangout. And you’ll love having everything conveniently contained – without sacrificing floor space. Let’s go up not out!

Two Levels Allow Cats to Climb and Play

One of the biggest perks of a double decker litter box is that it provides extra vertical space for your cats to climb, play, and explore. Cats love to be up high, and a multi-level setup allows them to fully indulge their climbing instincts.

Adding ramps and stairs between the lower and upper litter tray gives your cats easy access to move between levels. They’ll enjoy scaling the ramp or hopping up the steps to reach new heights. The upper litter box can become a coveted cat hangout spot.

Vantage Points for People Watching

Build a Double Decker Litter Box: Make Use of Vertical Space

From their new elevated viewpoint, your curious kitties can gaze out windows or monitor household activity. Cats are such inquisitive creatures, and access to an upper perch can provide enriching sensory stimulation.

Set up a cozy ledge or perch next to the top litter box so your cats can comfortably look out. But avoid placing it directly over the lower litter tray for sanitary reasons. Allow them to survey their territory in style!

New Spots for Cat Naps

We all know cats love to sleep, and the upper level of the double decker setup offers prime real estate for cat naps. The top litter box area provides a sense of safety and seclusion perfect for snoozing.

You can even attach a comfy cat bed or blanket to the upper level’s wall to create an irresistible napping nook. Your cats will fight over who gets first dibs on the top bunk!

Jungle Gyms for Play Time

In addition to lookout spots, the vertical space is ideal for playtime. Attach or hang cat toys like feathers, bells, and balls from the upper level to turn it into a feline jungle gym.

Place toys strategically to encourage your cats to climb up and enjoy some interactive play. Just be sure to position dangling toys away from the litter boxes to avoid contamination. This stimulates body and mind.

Cathartic Cat Scratching

Don’t forget to install a sturdy cat scratching post connected to the double decker setup. Scratching satisfies your cats’ innate desire to mark territory and sheath old claw sheathes.

The scratching post lets them stretch and scratch to their heart’s content. Position it for easy access from lower or upper levels. A vertical scratcher mimics tree scratching in the wild.

Litter Box Options for Picky Cats

With two litter boxes, you can cater to cats that prefer different litter substrates. Perhaps one cat likes clay while the other goes for clumping. Or some fancy crystalline litter over plain sand.

The options are endless with a double decker setup! You can accommodate multiple preferences while keeping the boxes in one space. Happy cats, happy home.

So don’t underestimate the power of vertical real estate for your felines. A double decker litter box setup lets them fully unleash their climbing and playing potential. Happy climbing, cats!

Easy DIY Construction with Wood or Wire

Build a Double Decker Litter Box: Make Use of Vertical Space

Feline friends bring joy and companionship into our homes, but their litter boxes can take up precious floor space. An innovative solution is to build a double decker litter box, making use of vertical space to house two litter boxes stacked on top of each other. This allows cats to have their own dedicated spaces while maximizing your square footage. Constructing a double decker litter box is a relatively easy DIY project that can be customized to suit your home’s style and your cats’ needs.

Planning Your Double Decker Litter Box

When embarking on this DIY endeavor, first consider your cats’ habits and specifications. Will two litter boxes be enough for your furry family? Some multi-cat households may require three or even four litter boxes. Also factor in the size – kittens and senior cats often need bigger boxes with lower sides for easy access. Make sure to get your cats’ approval before drastically changing their facilities!

Next, decide on the litter box style – covered or open top – and find boxes that fit your criteria. Measure the dimensions to determine the frame size. Opt for a streamlined rectangular or square shape to efficiently use floor space. Also check the height of your ceiling to ensure the stacked boxes will fit underneath.

Now consider the aesthetic – what style will complement your home’s existing design? Sleek modern wood, rustic timber, or industrial metal can all work for a double decker litter box station. Painting or staining will allow it to blend in or stand out.

Construct the Litter Box Frame

Build a Double Decker Litter Box: Make Use of Vertical Space

For sturdy construction, a wooden frame is best. Use plywood or 2×4 boards to build a rectangular box frame, with outer dimensions sized to snugly fit the litter boxes. For stability, include vertical boards on the ends and one or two in the middle dividing the upper and lower compartments.

Metal wire shelving units can also work for a quick and inexpensive litter box station. Look for heavy duty, coated metal wire racks intended for garage or industrial use. Or get creative and upcycle old iron bed frames, oven racks, or safety railings!

Be sure the frame is high enough to allow easy human access to clean the boxes. And include a way to securely attach the upper level so it does not shift or sag under your cat’s weight. Consider adding corbels, brackets, or other decorative supports for style points.

Add Entry Points for Feline Access

Now that the structural frame is built, it’s time to create entry and exit points for your cats. Cut openings in the front, side, or top of the frame for the kitties to come and go freely. The entryways should be tall enough for your largest cat to fit through with a few extra inches to spare.

You can attach acrylic sheeting around the entry areas to help contain litter messes. Hanging decorative curtains can also work for a cozy feel. Just avoid heavy fabrics that may inhibit air flow.

Elevate and Decorate the Double Decker Litter Box

Install the litter boxes inside the framed enclosure, securing the top level safely in place. Consider adding carpet, tiles, or a litter catching mat on the floor below the entry points.

Now have fun decorating your new double decker litter box station! Paint or stain the wood a bright color, or opt for a natural wood look. Add molding trims or cabinet handles for extra flair. Attach cute cat themed hooks nearby to hold scoops and cleaning supplies. Top it off with a cushion, plants, artwork, or other personal touches to make it both stylish and functional.

Maintaining a Multi-Level Litter Box

Cats are notorious for being picky about the cleanliness of their bathroom facilities. Be sure to scoop solid waste at least once daily from a double decker setup. Dump, wash, and refresh the litter every 1-2 weeks or whenever odors arise.

Check that litter is not getting tracked or scattered outside of the boxes. Trim down curtains or sheeting if needed. Wipe down any surfaces where litter accumulates.

A double decker litter box takes a bit more effort to keep clean. But the vertical design allows you to accommodate multiple cats in style! With the right planning and customization, this DIY project can give your feline friends their own penthouse potty while maximizing space in your home.

Include Ramps or Stairs Between Levels

Build a Double Decker Litter Box: Make Use of Vertical Space

If you have multiple cats, you know the struggle of trying to find enough floor space for multiple litter boxes. My two fur babies, Whiskers and Fluffy, were constantly getting into litter box disputes over who got to use the box first. After one too many unsanitary incidents on my floors (I’m looking at you, Whiskers!), I decided it was time to build them their own double decker litter box.

A double decker litter box allows you to make the most of vertical space. By building upwards, you can have two litter boxes stacked on top of each other without taking up any additional floor space. This is perfect if you live in an apartment or small home where real estate is limited. Plus, having two levels reduces litter box traffic jams since each cat can have their own dedicated space.

Pick a Location

When deciding where to put your double decker litter box, choose a spot that’s out of the way but still easily accessible for your cats. I put mine in the laundry room so it wasn’t taking up space in the main living areas. Make sure to place it on a non-carpeted floor. Tile, wood, or concrete floors are ideal as they will be easy to keep clean if there are any litter messes.

Build a Sturdy Frame

Build a Double Decker Litter Box: Make Use of Vertical Space

The frame is key to keeping a double decker litter box from toppling over. Use thick, heavy wood and secure all joints tightly. I used 2x4s to construct the frame and made sure to attach the posts with several screws and generous amounts of wood glue. The frame should be wide enough to fit two standard litter boxes across. Be sure to measure your cats’ litter boxes before starting construction.

I painted the wood frame white so it would blend in with my laundry room walls. You could also stain it a natural wood color. Just make sure you use a pet-safe, non-toxic paint or stain since cats will be in close proximity.

Include Ramps or Stairs

Going up and down between the two levels is tricky for cats, so be sure to include a ramp or set of stairs. I built a ramp with wooden boards and carpeted it so my cats would have good traction. You could also use a pre-made pet ramp designed specifically for cats and small dogs. Just secure it tightly to the litter box frame.

Stairs are another option if you have the space for them. Ensure each step is deep and wide enough for a cat to comfortably climb up and down. Having 3-5 carpeted steps makes for a gradual incline they can easily manage.

Add Litter Boxes and Lids

With the ramp or stairs built, simply slide your cats’ regular litter boxes onto each level of the frame. I put Fluffy’s on top since she likes to be up high. Make sure the boxes fit snugly so they don’t shift around or tip over.

You can build lids for each litter box to contain the mess and smells. I used thin pieces of plywood cut to size and attached them with hinges. Small hooks on the front keep them closed when not in use. Just be sure the lids are light enough for cats to push open when entering or exiting the boxes.

Consider Privacy Panels

Some cats prefer privacy when doing their business. To give them that, you can attach panels around the sides, front, and back of the litter box frame. Leave one side open for accessing the ramp or stairs. Use cardboard, pegboard, or plexiglass to make simple panels that block line of sight but still allow for ventilation.

Add Litter Box Mats

Litter box mats below each level will catch any stray bits of litter your cats track out. You can find mats in various materials like plastic, silicone, or honeycomb fiber. Place each mat centered under the litter box opening and secure them to the floor with double sided tape.

Be sure to get mats with raised edges to contain litter within the mat itself. Easy-to-clean silicone mats wipe up nicely for quick maintenance.

Maintain Regularly

Build a Double Decker Litter Box: Make Use of Vertical Space

Like any litter box, a double decker needs regular maintenance to stay fresh and clean. Scoop solids out of each box daily and change the litter completely every 1-2 weeks. Use mild soap and water to wipe down the frame and ramp/stairs when you notice dirt buildup.

Check that the structure remains sturdy over time. Tighten any loose joints or replace damaged parts as needed. Also trim nails of cats using the ramp to prevent them from getting caught or scratched.

With a spacious double decker litter box build, your cats can finally have their own dedicated potty spots. No more fights over who gets to use the facilities first! Just be sure to reinforce the frame, add a cat-friendly incline, and maintain it regularly so your cats can enjoy safe and sanitary comfort.

Add Privacy Panels for Shy Cats

When you have multiple cats sharing a home, sometimes they need a bit of privacy, especially when taking care of business in the litter box. My shy kitty Luna always waited until the other cats were out of the room before sneaking into the box. I knew she needed her own secluded space. That’s when I decided to build a double decker litter box with privacy panels for my shy girl.

A double decker litter box makes use of vertical real estate to stack two litter boxes atop each other. Adding in privacy panels creates a cozy, hidden potty area for timid kitties. The panels block the view in and out of the litter box so cats can relax and feel secure.

Pick a Private Spot

Build a Double Decker Litter Box: Make Use of Vertical Space

When choosing where to place the double decker litter box, look for an out of the way spot in your home. I put mine in the basement, tucked in the back corner behind the stairs. The basement doesn’t get much foot traffic from humans or felines, so it’s perfectly peaceful.

If you don’t have a basement, look for another secluded nook. A spare bathroom or closet works well too. Just make sure it’s still easily accessible for your shy kitty.

Build a Sturdy Frame

Don’t skimp on the frame – it needs to be super sturdy to support two litter boxes and panels. Use thick lumber like 2x4s secured with wood glue and screws at every joint. Measure the interior to fit your cat’s litter boxes exactly so they don’t shift around.

Consider adding diagonal beam supports on each side of the frame for extra stability. The last thing you want is for the whole structure to come crashing down!

Include a Low-Entry Point

Shy cats often prefer a low, wide opening to enter their litter box instead of climbing stairs or a ramp. Cut a opening in one side of the frame at floor level. Size it big enough for your largest kitty to easily walk through.

You can add a small lip or barrier on the floor under the entrance to catch stray litter. Just keep it under an inch tall so it’s not a tripping hazard.

Add Privacy Panels

Now for the privacy panels! Measure and cut panels from 1/4″ plywood, cardboard, or plexiglass. Attach them on the sides and back of the frame using screws or heavy duty double-sided tape.

Leave the front completely open so your shy cat doesn’t feel too enclosed. The side and back panels block the view enough to give them security.

If you have a kitty who prefers a fully enclosed space, you can add a panel to the front with a cat door cut out. Just make sure the door is big and easy to push through.

Include Hideaways Inside

For extra shy cats, add some small cardboard or fabric tunnels inside the litter box frame. Your timid kitty can hunker down inside while doing their business for maximum privacy.

You can also place a cat cube bed or small cardboard box on the floor inside. Offering a cozy hideaway helps anxious cats feel secure.

Add Litter Boxes and Mats

Insert your cat’s regular litter boxes onto the upper and lower levels of the frame. Place absorbent, easy-clean mats underneath to catch any spilled litter.

Consider getting a lower-sided litter box for the bottom level so your shy cat can easily climb in and out.

Keep It Clean and Inviting

Build a Double Decker Litter Box: Make Use of Vertical Space

To encourage your timid kitty to use their new private facilities, keep it clean and stocked with fresh litter at all times. Scoop every day and do a full litter swap weekly.

You can spray some synthetic feline pheromones inside to make it more welcoming to your shy cat. And be sure to give them lots of treats and praise when you catch them using the box!

With a sturdy double decker frame, privacy panels, and some cozy hideaways inside, your skittish cat will have their own perfect potty oasis. They’ll be able to relax and feel secure while taking care of business in their new secluded space.

Use Sifting Litter Pans to Contain Mess

When you have multiple cats sharing a home, litter box messes can get out of hand fast. I was constantly sweeping up wayward litter that my two furballs kicked out of the box. I knew there had to be a better containment system. That’s when I discovered sifting litter pans – the perfect solution for my double decker litter box.

Sifting litter pans have a grate or screen bottom that allows litter to fall through while catching solid waste on top. This keeps the box cleaner and contains the mess inside. No more litter all over my floors!

Pick a Convenient Spot

Build a Double Decker Litter Box: Make Use of Vertical Space

As with any litter box, choose a location that’s easy for your cats to access but out of high traffic areas. I put my double decker box in the basement near the stairs. The tile floor there also makes cleanup easy.

Make sure to leave plenty of clearance around the box for you to access the sifting pans inside.

Build a Sturdy Frame

Use thick lumber and reinforce all joints to construct a frame sturdy enough to hold two loaded litter pans. I used 2x4s secured with screws and wood glue for maximum stability.

Size the interior opening to fit the sifting pans with a little room to spare – you don’t want them jammed in too tightly.

Add Litter Pan Risers

Elevating the sifting pans makes it easier to deal with waste and keeps litter corralled in the pans. I built simple risers by screwing small boards together into a frame for each pan to sit on.

You can also buy pre-made grate risers specifically sized for litter pans. Look for heavy duty plastic or wire mesh designs.

Include Litter Catchment Ledges

Even with sifting pans, some litter still gets kicked out. Adding a small ledge around the interior perimeter of the litter box frame catches stray pieces before they hit the floor.

Use scrap pieces of wood to create simple catchment ledges around 2-3 inches wide. Just be sure to round off any sharp edges for safety.

Use Sifting Litter Pans

Now for the sifting litter pans! Look for pans with a fine stainless steel mesh screen bottom to allow waste to fall through while trapping litter on top.

I like using two jumbo size pans in my double decker box so my cats have plenty of room. Just be sure the lip around each pan edge isn’t too high for cats to easily climb over.

Add Absorbent Pads

Place absorbent pads underneath the sifting pans to soak up any liquid that seeps through. Pee pads designed for dogs work great. Change them out every few days or whenever you notice significant dampness.

You can also try litter box liners or incontinence pads to absorb odors and messes under the pans.

Maintain Daily

Build a Double Decker Litter Box: Make Use of Vertical Space

The whole point of sifting litter pans is convenience while keeping your space clean. Get in the habit of sifting out waste from each pan daily. Simply separate the tray from the base and discard any clumps.

Also sweep out any litter from the catchment ledges each day. Deep clean the pans and full litter change as needed.

With a sturdy double decker setup and sifting pans inside, you can easily contain litter messes while keeping boxes fresh. Just be diligent about daily sifting and waste removal. Your cats will love their clean new facilities!

Install Odor Absorbing Air Filters

When you have multiple cats using the same litter box area, odors can build up fast. No matter how clean I kept the boxes, my small laundry room always smelled a bit funky. I knew I needed to add some odor control when I built my double decker litter box enclosure.

Installing air filters with activated charcoal is an easy way to absorb litter box odors. The charcoal attracts and neutralizes smelly particles in the air, leaving your space fresh. It’s the perfect addition to any multi-cat litter setup.

Choose an Open Floorplan

Build a Double Decker Litter Box: Make Use of Vertical Space

To maximize air circulation, install your double decker litter box in an open area of your home. I put mine in the open laundry space off my kitchen. Bathrooms also work well since odors dissipate easily.

Avoid small, enclosed spaces that can trap odors. Opt for tile, concrete or wood floors for easy cleaning too.

Build a Vented Frame

Allow for plenty of airflow in and out of the litter box enclosure. I constructed my frame from slots and spaced boards to keep it open while still concealing the boxes.

You can also add vents along the upper sides of the enclosure. Just make them big enough for air to pass through but too small for kicking out litter.

Add Hanging Air Filters

Look for air filters designed to hang right inside the litter box enclosure. I attached two large activated charcoal filters to the upper interior sides with heavy duty command strips.

Make sure to change the filters every few months when they become saturated. Check that air can flow freely around the filters.

Use a Filter Fan Unit

For maximum odor control, install a fan powered air filter unit. Mount it high on one wall or ceiling of the litter box area and angle it to point inside the enclosure.

Look for a quiet model so it doesn’t scare your cats. And be sure the cord is safely secured away from curious kitties.

Open Nearby Windows

Improving overall ventilation in the room helps clear odors too. If possible, open windows on opposite walls to create cross breezes across the litter box.

You can set windows to vent mode to circulate fresh air inside. Just remember to close them before leaving cats unsupervised.

Use Litter Deodorizers

While the air filters work to trap odors, deodorizing litter products help neutralize smells at the source. Look for litters with baking soda or activated charcoal added.

Sprinkling a bit of odor eliminating powder into each box every few days helps too. Scoop waste daily before smells set in.

Add Litter Mats

Litter catching mats below the litter boxes help minimize odor-causing tracking. The best mats have a mesh or grated surface to let litter fall through.

Be sure to shake or vacuum mats daily to remove waste particles before they can really smell.

With open construction, air filters, ventilation and deodorizers, your double decker litter box can stay surprisingly odor-free. Just be diligent with maintenance and air circulation so smells don’t linger.

Hang Toys from Top Level for Enrichment

Build a Double Decker Litter Box: Make Use of Vertical Space

When building a double decker litter box, don’t forget to add some fun for your cats! Hanging interactive toys from the upper level keeps cats engaged and provides mental stimulation. My furballs Lucy and Jax loved batting around the toys I attached inside their new enclosure.

Dangling feather wands, crinkle balls, and catnip mice from the top floor turns a practical litter box into a playful jungle gym. It’s easy enrichment you can include in any double decker build.

Pick a Playful Spot

Look for an area with open floor space around the litter box so your cats have room to play. I put mine in the spare bedroom since it gets lots of sunlight and has low traffic.

Make sure to keep the location out of high traffic human zones so toys don’t get in the way. A bedroom, office, or laundry room tends to work well.

Build a Sturdy Frame

Reinforce the frame with thick lumber and secure joinery. The upper level needs to support active cats batting hanging toys without shaking or swaying.

I used 2x4s for the uprights and thick plywood for the upper and lower platforms. For safety, round off any sharp corners on the wood.

Include Overhead Beams

Build a Double Decker Litter Box: Make Use of Vertical Space

Adding horizontal beams across the top of the frame gives you anchor points to hang toys from. Use wood boards, dowels, or metal poles secured at each side of the frame.

Space beams every foot or so to give you plenty of hanging points. Check that beams are high enough for cats to walk underneath.

Hang Interactive Toys

Now for the fun part – dangling toys! Tie or clip cat teasers like feathers, wands, balls, and mice to your overhead beams using sturdy string, cord, or twist ties.

Vary the height so some toys hang low enough for cats to bat while standing and others require jumping from lower levels.

Add Shelves for Toys

Include flat shelves mounted on the walls of the enclosure for placing interactive toys like treat puzzles, rollers, and catnip kicked.

You can also install cubbies or hammocks to store toy collection. Just be sure shelves and mounts are securely attached.

Incorporate Scratching Surfaces

Glue or screw sheets of sisal rope, corrugated cardboard, or scratching mats onto the inner walls and platforms. More surfaces to scratch keeps cats coming back.

You can also hang small scratching posts from upper beams. Use sturdy mounting brackets to attach them.

Rotate Toys Frequently

To keep your cats interested, swap out dangling and stationary toys every week or so. Rotate in new teasers and puzzles to pique their curiosity.

Spritz toys with catnip spray occasionally for an added draw. Watching your cats play will be as fun as building the box!

With a double decker litter box equipped with toys, your cats can stay entertained for hours. The vertical setup lets you maximize play potential in any unused corner of your home.

Place Mats Under Boxes to Catch Spills

When you have multiple cats using a double decker litter box, inevitably litter gets spilled outside the boxes. My furry friends Midnight and Salem were pros at kicking litter all over the floor around their enclosure. Placing absorbent mats under the litter boxes helped contain the mess.

Litter catching mats on each level trap spilled litter and absorb any liquids or odors. They keep the main floor around the box clean and tidy. Mats are an easy add-on when constructing any multi-level litter box.

Pick an Open Floor Plan

Build a Double Decker Litter Box: Make Use of Vertical Space

Choose an area with open floor space around the litter box enclosure. This allows room for you to easily place mats and makes cleaning up kicks and spills simpler.

I put my double decker box in the open laundry/utility room. A bathroom, mudroom, or kitchen also tends to work well.

Build a Ledge for Mats

Construct a small lip or ledge around the interior edge of each level to hold mats in place. I used thin wood strips secured with nails around the front and sides.

The ledge needs to be just high enough to secure the mats, usually around 1-2 inches tall. Smooth any rough edges for safety.

Choose Absorbent Mats

Look for mats made of moisture-wicking and odor-controlling materials like microfiber, charcoal foam, or silicone. I prefer machine-washable mats for easy maintenance.

Make sure mats are large enough to fully cover the open area under and around each litter box with a little overhang.

Secure Mats to Floor

To keep mats from shifting around, secure them to the floor using double-sided tape around the edges. You can also use Velcro strips on the mat bottoms and floor.

For upper levels, tie mats securely to the ledge using durable outdoor cable ties threaded through mat grommets.

Clean Mats Frequently

Build a Double Decker Litter Box: Make Use of Vertical Space

Scoop litter off the mats daily using a broom and dustpan or handheld vac. Shake mats outside or vacuum thoroughly to remove all debris clumps.

Remove mats weekly to launder according to manufacturer instructions. This prevents odors and stains from setting in.

Replace mats every 4-6 months when they start to show wear and lose absorbency. New mats make the box setup look clean too!

With absorbent mats stationed under all litter boxes, you can easily keep surrounding floors pristine. Just be sure to clean mats regularly so they continue effectively trapping all the mess.

Keep Litter Boxes Clean with Frequent Scooping

When you have multiple cats sharing a double decker litter box, regular cleaning and scooping is a must. Waste piles up quickly with high traffic boxes. I learned that the hard way when my cats Pixel and Leo started avoiding their messy double decker setup.

By scooping all boxes twice per day and swapping litter regularly, I was able to keep their litter boxes pristine. Proper maintenance is key for any successful multi-cat litter setup.

Give Cats Access

When deciding where to place your double decker litter box, make sure it’s in an area you can easily access twice daily. I keep mine in the open laundry room which I pass through often.

A spare bathroom or open closet works too. Quick access lets you stay on top of scooping before smells set in.

Use Clumping Litter

Clumping litter makes scooping faster and easier. The granules form solid clumps around waste to quickly remove. I prefer lightweight, dust-free clumping litter.

You can use the same litter in all boxes or offer different types on each level to give cats variety. Just be sure it clumps firmly.

Invest in a Good Scoop

A sturdy scooper with deep sides makes quick work of litter cleaning. Look for a metal design with comfortable grip and serrated edge to easily slice through clumps.

I keep one scoop permanently in my laundry room so it’s always handy when needed. A scoop with its own caddy is convenient.

Scoop Morning and Night

Build a Double Decker Litter Box: Make Use of Vertical Space

Get on a schedule of scooping every single box first thing in the morning and right before bed. Consistency is key – cats like a clean space.

Remove all clumps and solid waste. Then give the litter a quick stir to aerate it. Be thorough but quick so boxes are never dirty for long.

Fully Swap Litter Weekly

Even with diligent scooping, litter gets saturated with odors and urine over time. Do a complete litter change in all boxes once per week.

Dump all used litter and fully wipe out boxes with gentle cleaner. Add fresh litter to each box level 2-3 inches deep.

Regular deep cleaning keeps boxes smelling fresher longer.

Staying on top of daily scooping and weekly litter swaps helps maintain a pristine litter setup. Your cats will thank you for keeping their bathroom space clean!
