One of my cats is an avid digger before and after using the box, so this has helped contain a lot of the litter. There is still some stray litter if he goes bananas, but it is way less than before.

Definitely helps to keep litter in the box! And keeps the kitties from pooping over the side!

This one is a lot taller than the wall that comes with the machine. One of my cats was constantly kicking litter everywhere with the old one. With this new taller wall, very little gets kicked out of it.

The higher entry wall is great except my old cat and he’s like 22 pounds huge he probably needs a step to get up and into the box easier.

My cats were making a mess with the shorter wall, the larger wall takes care of that.
