Hey friends, this is not an ad, just wanted to share something I found last night when I was shopping for ferret stuff. It is a heated bed/house for cats. But I feel like it could work for ferrets too, so I photoshopped some as an example:). It is heated and is designed for outside cats, but some may want to use these if their homes get cold, it is much more energy efficient than running AC all day for your cats/ ferrets when you are away. I haven't used it yet, so I don't know if it is actually good, but sounds like a nice idea.
