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.

My 3 cats were kicking litter out like crazy before getting this higher wall. Very good choice!!!

We are loving the top entry wall for our two extremely enthusiastic diggers. It helps keep litter in the box!
