Hello, I know this is no big deal, but I am wondering why Tuffy has all of a sudden changed from his normal sleeping spots. I could almost always find him sleeping on his pillow by the window or in my old rocking chair. But as of the last couple days he spends alot of time sleeping in the pet carrier. There is a old wool sweater in there. Could this be some instinct learned from wild cats? Not to stay in the same spot for to long? I am not worried about him, just wondering why cats do some of the things they do.
