No matter what we try he won't stop scratching the wall next to his litterbox while trying to bury his shit. The only thing that works is physically blocking him from scratching the wall, but the only thing I can think to put between his box and the wall is a shoerack, which I would really like to be able to use without the risk of shoes falling into his litter. We're in a small apartment so working with very limited space and can't just have it pulled away from the wall. Just wondering if anyone has any ideas on what to replace the shoe rack with
We've had a lot of cats, some of which have wanted to scratch more than the litter. The simplest solution is to get a litterbox that has a cover. Some of those have doors, too, and you might have to remove that because some cats won't use them. A side benefit of the cover is that you won't get much litter flung out of the box.
I'm hesitant to buy one because weirdly enough he seems to be claustrophobic but I might try.
They have some with open tops and high sides.
To add to the other lemming's reply - if you can't find one of these of your liking or with high enough walls, you can always buy a storage container tub and cut out a U shape on one side to be used as door.
