Thanks for all of your suggestions! Caleb has been to the vet, and they said that he had colitis, because I give him a variety of food, and he wasn't used to some of the food I was giving him, so it was irritating his colon which gave him bloody diahrrea, but other than that, he's perfectly fine. He was litter trained before he came to me. He was on pine shavings, and he's on pine pellets now. I'm going to change the litter to something else anyways because I don't like the smell, and with him in such close proximity to the litter box while he's crated, I'm afraid he'll develop some respiratory problems from the phenols in the pine. I've been crating him in my room every night now. He cried at first, but he's gotten used to it. But the little bugger dragged his blanket into his litter box and peed on it! With not letting him in my room unless he's in the crate, and trying to keep my laundry away from him, he's only had one more accident. I changed out of my clothes and accidentally left them on the floor, and he peed on those.
