Lilee also wears jammies and has blankets, but I got some great advice by a YT member Spritwings1202. She told me about the SnuggleSafe so I went out and bought one, found it at Pet Club here in CA. You warm it up in the microwave and it keeps the heat for up to 8 hours. It also comes with a fleece cover and I put it under Lilee's bed. It's keeps her nice and toasty although she often ends up cuddled with me
