Bests & Worsts Reviews from Amazon

I really wanted to like it, but even the length of the outside of the box (including the rims) is a bit less than 19in. The inside is about 16in in length. My cat is 16in from the neck (from where her collar sits) to her bottom. That means that if she goes in the box straight, not diagonally, she pees on the rim! And the pee slowly seeps down the front of the box and under it... every day. I tried to find a bigger open top box from IRIS but couldn't find one. I thought I'll try it some more and I was able to kind of contain the situation by using a liner bag in the box and pulling the bag's sides up around the rim. This made like a little "pee catching moat" around the box. But that means when I cleaned the box I had to check the moat for pee and gather it with paper towels & wipe everything with wet wipes. Today I give up. My cat is a big thrower of litter out of the box. That's why I wanted the tall shield but with an open top, since I know cats don't appreciate the closed ones. But this one is not the right now. Switching back to her old box (longer, though not shielded high enough). At least, sweeping litter everyday is easier than cleaning the pee moat. Still searching for the perfect litter box...
