Yesterday, my roommate found a ridiculously nice stray cat. It followed her to our room, and we brought it inside because it's very cold here at night. He was absolutely thrilled, and without a way to get cat food, we got him unseasoned turkey to eat. He was in love with it, and has been eating it since. He has eaten a lot, and has been drinking regularly. However, we haven't seen him pee or poop at all. We made him a box with newspaper inside it, but he is uninterested. I've checked around pretty well, and I haven't seen/smelled any evidence of anything. We think that he was probably a house cat that got lost or something, but he has a matted tail and no collar. He sleeps a lot, but isn't feeble at all and follows us around. Should we be worried? It's only been a day.. I might just be overreacting. Do you think it's possible that he won't go inside because he used to be a house cat and has no litter box? Oh, and I've had cats all my life and my mom owns a pet food store; I know that turkey isn't the best thing for him, but we are getting real cat food ASAP. Thanks in advance for the help, guys.
