We recently took in 2 foster kitties. They're doing fine, aside from an eye infection that I am unsucessfully treating (can't always catch them to give them eye cream) But we have a problem. The first night, I found that they'd poo'd in the living room, in a corner, and in the computer room behind the couch. No biggie, they just aren't used to the apartment. I cleaned it up, sprayed with citrus air freshener and Nature's Miracle. No problems there. The problem is with the bathtub! For some reason, one or both cats keeps poo'ing in our bathtub! They also were pee'ing in there, as well as in our shower when I left that open overnight. I keep the shower closed now, and I put a litterbox in the bathtub. But every morning when I get up, there's another pile of poo in the bathtub! It's really getting annoying. They're not peeing anywhere else (I've gone over the apartment about 4 times with my blacklight) and using the litterbox correctly during the day. It seems like it's only overnight. We have 3 litterboxes, 2 covered and one uncovered. They have access to one covered and the uncovered all night long, and we keep the other 3 cats locked into the bedroom with us all night. I can't figure this out!
