Contrary to what you may think, bears aren't the only animals that spend the winter in caves. Here I am in my parrot cave, busily chewing away. You can see that I have quite a stack of books to chew through, not the least of which is the Central Vermont and New Hampshire phone book (2011). I guess I have enough to keep me busy until it's warm enough to go outside for walks in my carrier. Probably that'll be about the same time as the bears emerge.
