I have 2 cats, and they seem to hate each other. They have been for a long time and they just don't get along. But one of them (the female) always uses the litterbox. The male never uses the litterbox. I doubt it's because its not clean enough, since we have 4 different litterboxes with 3 different types of litter.
He does seem to pee in the litterbox though. We haven't seen any pee on the floor so far at least. This has been going on for years, but it wasn't a problem before since he was an outdoor cat. We moved to an apartment recently and we can't have him as an outdoor cat anymore. We think it is because he is unhappy and wants to go out and also doesn't get along with the other cat. We have tried everything, but he still poops on the floor. What do we do?
If we can't solve the problem then we're just going to have to release him outside and not take him back again. We feel like its the right thing to do since its a pretty small apartment and he's lived his whole life as an outdoor cat. He also doesn't like the other cat. Can't be a fun life for him in here.
