Well, the piggies new hutch has finally arrived and I have a few questions! I'd like to start keeping the piggies on fleece in their bedroom, but not sure how everyone does it. Is it newspaper, a towel then the fleece! ? And is this suitable for all times of year? Do * have to use any small animal bedding on top of the fleece, for burrowing and warmth or not? I notice some people have what look like cat beds! Do the piggies like these?!
