Perfect for what it is.

I purchased this to fit inside my litter box enclosure. One thing I like about this litter box is that the sides are not weak or flimsy, a problem that I've encountered with many plastic litter boxes. This one is strong enough to be picked up by the upper rim, and when I'm changing out the litter, that's a big deal. My tip for others who want this for their litter box enclosure: This box works well for my situation EXCEPT for one of my kitties, who is a big boy (14 lbs) with long hair, he has some trouble climbing into this litter box when it is inside the litter box enclosure. I removed the optional inner partition wall that has the cut-out entrance, and this seemed to make it easier for him to get in and out. It was just too cramped for him otherwise. I will be trying out a low-sided litter pan to see if that makes it even easier for him. I certainly will be keeping this litter box though. It's stronger than my hooded ones. I got a good product at a good price, so I'm very pleased.

No more litter on the floor!

Finally found a sturdy litter box with high sides that fits into the small space in my bathroom. The sides are high enough to stop my cat from kicking litter and dust all over the floor. It’s definitely an improvement.

Great Litter Boxes

I like these litter boxes because there is no splash on my walls anymore if you get my drift. My cats love the privacy when they go. The litter boxes are thick and sturdy. I am very pleased I bought four. Frisco is a great company. I have their cat dishes as well.

Not large enough for adult cat

This litterbox seems well-made and the high sides are a plus, but it is not long enough for an adult cat to move around in - I bought it for my mother’s senior kitty who weighs 9 lbs and her urine went over the low front because the box was too short. It should be fine to use with kittens.

Perfect fit

Bought to fit in a litter box end table enclosure. The sides are nice and high and hopefully will keep the litter in the box. Our old pan had the attachable part that made it taller but it wasn’t very tall and was just another piece to clean the poo and pee off of and the litter and poo would still find it’s way over the sides. Very happy with the size and height of this box.

my cat likes it, much needed space

My cat would sometimes miss the mark on his old pan, where the walls were not very high at all and there wasn't a lot of room. this new box solved the problem, he no longer messes on the floor, and there's plenty of room for the litter with a lot of depth so cleaning is easy and there isn't really any scraping. the plastic is also pretty sturdy.

Great size

Perfect for my litter box storage table. Fits nicely and high enough to keep most of the litter inside the box.

Exactly as described

My senior girl Betty needed a little help in the cat litter box area - she would do her business in the box but sometimes some of the business would get right outside of the box. With these higher sides I think she's more comfortable and there are no accidents. Highly recommend.

I can sling litter ANYWHERE

To be fair, this is a nice litter box but I am the kind of cat who likes to sling litter all over the place. Person set up this new box and filled it with the approximately 12 POUNDS of litter recommended. I used the box but there was so much litter in it that Person said it looks like I used a front end loader to move litter all over. I told person that an ordinary cat would do just fine in a box like this, but it isn't for me.

Perfect Fit!

It's a perfect fit for the litter box enclosure I purchased to hide the litter box. I have a main coon so he's big & the first one I purchased didn't have high enough sides but this 1 the sides are high so there is no spillage. It's perfect!
