The top entry wall has been great at keeping the litter inside the litter box. My cats are not bothered with either version. I use the ramp for the kittens and they can use the top entry wall. Highly recommend.

I have 3 cats. One cat never fully squats and constantly urinates over the origianal wall. This new high wall fixed our problem.

It got returned because I did not puck it up. However, I did not know it had arrived!

The higher wall is exactly as described. Unfortunately, my cat is a challenge. She will not turn around in the box, and needs a much higher wall than this. That being said, we made it work by affixing the original wall onto the top of the Top Entry wall. Now the box is truly top-entry and the wall is high enough to keep a mess from getting sprayed across the room, and just the right height to still be able to empty without issue. I would rate the box, overall 4 Stars, and the top-entry wall 3 Stars.

I really like the convenience of the litter box is very easy to keep clean and very easy to use
