## Description

Review: Good size for large cats - Perfect size for my large cat. Littler doesn’t stick. Easy to clean
Review: Great box for large cats! - I have seven cats and I wanted one to specifically replace a giant storage container that we modified to be big litter box. It works great don't get me wrong, but I wanted a large kitty litter with a door flap to help cut down on cat litter dust which this new litter box does. It's easy to take the top off to clean and has great space inside. Another issue I previously had was our 21lb kitty would always somehow manage to pee a fountain outside of our other litter box 🫠. This has completely stopped since getting this box. I have not had one speck of urine outside of the box and it's the best thing ever for this kitty Momma lol! My cats range from 6lbs-21lbs so having a large box is vital lol. This box is exactly what I wanted!

### ⭐⭐⭐⭐⭐ Finally, a cat box solution for my big boy!
*by B***J on 29 May 2026*

I have a big cat who “aims high”. I’ve tried several different boxes and have had to clean up floors and walls and was left with odor. I decided it was time to spend the money, get a good box and be done with it. I couldn’t be more pleased with this purchase. The only negative is my cat does not like the flapping door, so I took that off. There is no detectable odor like you get with plastic. It’s easy to maintain, durable, and should last a long time. Cat and I agree - 2 paws up!
