So Phresh Scatter Shield High-Back Litter Box Grey Large 18.5" L X 15" W X 8.5" H

The box seems small but I but it's more than adequate for my average sized, full-grown adult cat. She did knock it over one time, trying to jump over the side, but I think it scared some sense into her and she's never done it again.This pan is very easy to clean! I'm a horrible cat Mom and just completely dump and change the litter box once a week.... everything slides right out. My cat urinates in the same spot and all I had to so was give that build up of litter a little nudge with my scooper and it came right out. Easy peasy.

It's a solid litter box. Just the right size for our needs.

My cat had an extra large litter box before and because she's 13 now, she recently developed a habit of peeing behind the box. She would pee and some of it would miss. So I've been searching for a litter box that would stop that mess. This is that box! I'm so happy I found this box. She started using it immediately. The bottom of the pan is coated so it makes it easier to clean the clumps as I use clumping litter. The only thing is the sides of the pan aren't coated with the same material so sometimes the urine may stick there but it's not bad.The opening of this box is also great because it's not super low to where all of the litter will end up all over your floor. I noticed that there was SIGNIFICANTLY less litter than with her old box on the floor. Even though my cat is kind of up there in age, she is still very active so the opening isn't a problem for her to climb over. However, if you have a sickly, disabled or really old cat this opening may be slightly too high. My cat is of average size ( 8-10lbs), and she has plenty of space to use. This box actually helps me save on litter because I don't have to put as much in to be used, and not a lot spills out so it's a win/win. Would definitely recommend this box to average cat owners whose cats aren't picky about where they go to the bathroom and also want to stop the annoying urinating behind the box. The sides are high enough that the urine doesn't even come close to coming out. Hope this helps someone.

These were exactly what I was looking for. They are the right size with the sides and back being higher and the coating is so slick it makes it super easy to clean.

Still had to buy some pee shields. But it's big enough and she seems pleased.
