About Frisco Litter Boxes

Durable Litter Box Options for Every Home

Durable Litter Box Options for Every Home

Frisco litter boxes give kitties a spacious, private spot to do their business. Each box is made for long-lasting use with durable, recyclable materials and high walls that help reduce litter scatter. With covered and uncovered boxes that come in several larger-than-average sizes and two neutral colors, there's a style that's perfect for every household.

Designed to Keep Litter Inside

Some kitties gently paw through their litter, but others tend to dig deep and vigorously until they're ready to go. Frisco designed their litter boxes to keep litter from spilling out, so you don't end up with more of it outside the box than in. Features like raised sides, high back walls, removable rims and covered tops help cut down on the time spent sweeping around the litter box.

Designed to Keep Litter Inside

BPA-Free and Made to Last

Only high-quality materials are used to create Frisco’s line of durable litter boxes. With BPA-free plastic, these boxes are made to last through numerous trips to the litter box. They’re easily cleaned with just soap and water, and eco-minded pet parents will appreciate that they’re recyclable, too.

Choose the Style That's Right for Your Cat

Frisco knows that cats have different preferences when it comes to their ideal litter box. That’s why they offer a variety of models to suit their needs—and yours.


High-Sided: Tall sides and back with a lowered front so that cats can step in and out easily. Available in two sizes with an open design that allows for quick spot cleaning.


High-Back: The high back wall and sides help keep litter and cat spray inside while keeping dogs and small children out. Extra-large size is great for big cats and multi-cat households.



Private yet accessible box has a cover to contain litter and a translucent door for added privacy. Includes a charcoal filter that reduces odors and a convenient handle for easy lifting.

Open Top With Rim

Open Top With Rim: Comes with a removable rim that not only helps to contain litter and spray, but also makes it easy to scoop and spot clean.

Deluxe Hooded

Deluxe Hooded: Has all of the features of the hooded box but comes in an extra-large size with a litter scoop and hidden storage compartment.

  • Great First Litter Box!

    By on

    Before bringing home my new cat, I purchased this litter box specifically because of the high sides. I am very glad I did because Willow is a litter flinger. The large size is perfect for her, something I was worried about. I didn’t want to crowd her in a small box. On a side note, I had accidentally added the XL size to my cart without noticing. After placing the order, I noticed my mistake. All it took was a simple reply to my confirmation email, and Chewy fixed my order promptly. Thanks Chewy!

  • Perfect size

    By on

    My cat is a bit of a prima donna with his litter boxes. They have to be jussssst the right size for him to feel comfortable to do his business. Not knowing that initially we had tried a smaller (shorter) box, and he would avoid it if possible in favor of the much older, (but larger) litter box in a different and less convenient location. So it made sense to make him happy by purchasing a larger box for the normal area. Especially for the price, this was a great buy. Good quality.

  • High back, compact size.

    By on

    Unlike most high-back boxes, this one will fit into my litter box "houses". Most are way too large for the average litter box house, but this one is perfect. If you use liners, I suggest getting only the jumbo size - the large barely makes it. Also - I use a 12" rubberband to hold the liner in place - the elastic and draw-strings don't do the trick, but the large rubber bands are perfect!

  • Great size

    By on

    Perfect for my kitty who feels he must dig to China before and after every use, and perfect for other cat, a tripod (front leg lame), as he can balance on the low side with support from the high sides. My husband had bought them a round-bottomed deep pan from an independent pet store, but it tended to tip/roll when my three-legged baby was inside, spilling the litter and frightening the kitty. This one has a square base and sits sturdily. He uses it with confidence.

  • Simple yet efficient

    By on

    It is a simple, yet efficient box. My cat likes to make a mountain every time she goes to the bathroom. Now I don't have half of the litter on the floor! The overall size of the box is great. I only have 1 cat, but I'm sure it works well with multiple. Love the color too!

  • Best Litter Box Ever

    By on

    Great quality and design. Better quality plastic than other litter boxes that I have purchased. The lower front entrance makes it easy for my cats, including my 19 year old, to get in and out of the box. The higher sides have eliminated over spills. I purchased this to fit in a litter box enclosure that looks like furniture. I accidentally ordered the 24 inch size and it was too large for the enclosure. Chewy customer service was excellent in resolving the issue. They shipped the correct size immediately and told me to donate the 24 inch box to my local shelter.

  • Highback litterbox

    By on

    Perfect for litterbox furniture. High back and easy to clean. Great for cats that like to go towards the back of the box. My female cat always goes towards the back and pushes litter high along the wall of the box. This box is perfect for her.

  • Low side isn't great

    By on

    Small diameter and low end defeats the purpose of high walls. Cats still dig litter out of the low edge. The high walls on other 3 sides do prevent overspray. The box is actually a bit small so if your cats are big you might find a larger tray.

  • This is the One

    By on

    This high sided BOX now makes a nasty job a very easy job. We have have 2 litter throwers and they love hearing the litter hit the high sides. It is the winner and it took just 5 minutes to find it and place the order, that only took 2 days to arrive. Super Service...Thanks R & C

  • Great size

    By on

    Perfect proportions for my elderly cat, no trouble getting in & no litter kicked out. We are both happy, however, this arrived with a corner broken off but still usable. Shipping box looked like it had been dropped !
