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

I wanted this because I have wild litter cats. It helps cut down on tracking and potential pee spray missing the box. Cats weren’t bothered at all. Good buy

The higher wall works much better than the lower wall, but some litter still gets out if your cat is an energetic digger. It is hart to justify an additional $45 when I still have to vacuum the area several times a week.

I have two cats, one is a digger and threw litter everywhere! There is still a slight litter mess, but only because it comes off their paws when they jump out! The best add on, you need this!

Great addition. My cat is a heavy digger and would throw a lot of litter outside the box with the standard wall. With the high wall it's reduced to almost nothing.
