So my cat, Kingsley, keeps pooping just outside the litter box in the kitchen! It's really annoying. We have the roll-over litter boxes with a top piece, and he is big, so it's a close fit. But I know for a fact he can fit in the litter box, because he can pee in there (and sometimes poop!) just fine. The boxes are cleaned each night, sometimes more often. He was a street cat before we got him, but he is healthy and has all his claws. So I just don't know what the problem is!
