Thread: Number of litter boxes

Well I've got two large cat boxes now. Cleaning the one out every day was not working out for Oliver, so I got a second one. He's still pooping in my shower, and I don't know why. I put the second box next to the shower, thinking if that's the spot he's picked as "his" it would be good. It can't be that it's dirty, because I'm constantly cleaning them. I'm worried that if I close the shower door he'll go somewhere more difficult to clean. Is he just doing it to spite me? He's not going in my husband's shower, so I'm wondering if it's personal. He seems to be getting along very well with Sterling, so I'm out of ideas. Help!
