The box is a decent size and the high sides are great. I wish the step was a bit more sturdy, and because it is inside the litter one of my cat urinates on top of it so the urine gets underneath the step. I have to remove the step and clean it so that makes it a little challenging. Also the box is a bit thin I wish it was a bit stronger material, and a bit pricey too. Overall a decent litter box. Just needs a few tweaks.
