The all-new Modkat XL Litter Box shares many of the traits of the original Modkat - the full-height seamless base, the reusable tarp liner, and of course the award-winning great looks! But all that’s just the beginning! We scaled up the XL to better suit larger cats and multi-cat households. Plus, you can use the XL as a top or front-entry solution, making it the most versatile litter box on the market.

One box. Two ways.

Modkat XL is the first dual-entry litter box on the market, offering both top-entry and front-entry configurations.

Top-Entry Configuration

When using the top-entry configuration with the full height reusable liner, the box keeps all the litter inside. It doesn't matter how vigorously your cats dig or where they aim. Whether they gently climb up or skittishly leap out, gravity pulls litter from their paws. To finish the job, the lid doubles as a walk-off mat, keeping your floors practically pebble free.
Top-Entry

Front-Entry Configuration

Modkat XL easily adapts for cats who are set in their ways or senior cats who require a front-entry solution. Simply pop out the front cover, switch to the included front-entry liner, and snap on the walk-off platform. The ample entryway makes it easy for kitties of all sizes to get in and out, and the walk-off platform helps reduce litter scatter and tracking.

Easy access, swivel lid.

The lid swivels open, ensuring any stray litter falls back inside, and it lifts straight off, providing full access for thorough cleaning.

Grand entrance.

Whether using the top-entry or front-entry configuration, the oversized openings make it easy for your kitties to use their Modkat XL.

Liners that last.

All Modkat litter boxes work with our exclusive, patent pending reusable liners. They are tailored specifically for each litter box to prevent messy gathering and unsightly bulges. Support hooks at each corner ensure the reusable liner stays put and make it a snap to empty and clean. Our liners are constructed from durable tarpaulin, so they are scratch-resistant, easy to clean, and last up to three months!

Reusable Liners

BPA free.

Modkat XL is made from BPA free ABS plastic, which is safe for your pet, bacteria resistant, and has a beautiful mirror finish.

If your cat loves jumping up on the windowsill or the arm of the couch, climbing into the sock drawer or that empty cardboard box, then your cat probably will use a top-entry litter box. Cats are naturally curious creatures and enjoy being on top and inside everything.

We do not recommend placing our products outdoors, as long-term exposure to direct sunlight may alter the finish and color, and extreme fluctuations in temperature may distort the material. This falls outside the intended use of this product and is not covered by our manufacturer warranty. Read more

Place your cat's litter box in a quiet location away from where they eat and drink. If your new litter box is replacing an old one, be sure to position it in the same, familiar location.

Scooping daily will keep odor in check and aid in keeping your cat healthy. Periodically add new litter to maintain the recommended 3-4 inch level. This will enable your cats to bury their mess properly while keeping urine from reaching the liner or the bottom of the litter box. Fully replace litter every 5-7 days. Wash the reusable liner and the litter box interior with low fragrance dish soap and warm water. Read more

All our litter boxes come with one of our exclusive Modkat Reusable Liners. These liners are made of commercial grade tarpaulin, which reduces ripping, odor absorption and liquid penetration. They last up to three months, and you can purchase replacements here. If your cat’s not the liner type, don't worry! All Modkat litter boxes feature smooth bottoms and seamless bases for easy cleanup.

Reusable liners last up to three months depending on how many cats use the litter box, how much litter is used, and how ferociously your cat(s) scratch. To get the most out of your liners, we recommend cleaning with mild dish soap and water monthly. Be sure to let the liner dry before putting it back in the box. Replace the reusable liner when there are signs of fraying, tearing, or excessive odor.

We recommend a clumping litter that's organic or all natural. Veterinarians, and many cat owners can attest that clumping litter beats clay any day. It is better for the environment and it works great with Modkat Reusable Liners.

If you change your current litter type, gradually introduce it over a 3-4 week period. Mix increasing quantities of the new litter with the one your cat previously used, ensuring your cat an easy transition to the new litter.

NOTE: To avoid confusion and any potential accidents, do NOT change litter type at the same time you change the litter box. 

How much litter should I use?
We recommend maintaining a 3-4 inch litter level at all times. This will enable your cats to properly bury their mess while allowing the litter to properly clump.

What's the best way to dispose of litter?
Dispose of litter with regular household trash. Litter and clumps should NEVER be flushed or poured down the drain. Cat feces may be toxic, and litter can clog your drain.

Cats like to have their own space, just like we do. It is best to have one litter box per cat, it will help to prevent territorial battles over the litter box and will make it easier for your cat to use the box whenever it feels the need. However, who has enough room for that? If your cats don't mind sharing a box, we just recommend scooping at least once a day.

When Modkat XL is used in it's top-entry configuration with the reusable liner it's very difficult for dogs to access. The top entrance is very hard for a dog to maneuver into. And, since XL has very little taper (only 1º) it's super stable, and practically impossible for a dog to tip over.

Top-entry configuration has a few advantages over front-entry configuration. If your cat scratches and scatters litter everywhere, or your cat sprays or pees sideways, top-entry will be your best bet. The top-entry liner is 14.5" (36cm) tall, and solid around the whole perimeter, this will ensure that anything your cat throws at it remains inside the box, where it belongs.

If your cat is obese, elderly, dissabled, or just stubborn and refuses to try top-entry, we've got ya covered too. We have a front-entry liner that is also 14.5" (36cm) tall and is solid except at the opening. At the opening we've provided a walk-off platform that keeps litter scatter at bay.
