We just bought a house and inherited a really sweet barn cat with it. I tried a few set ups to keep her comfortable when it's cold, but she wouldn't have anything to do with them. I contacted the previous owner of the house and she told me she just put a cat bed with a heat lamp on the patio for her so I put my baby chick brooding heat lamp out there next to this house and since she knew that light meant warmth, she started using it and quickly realized the bed was heated. Now I can put the heat lamp away and she stays nice and warm on cold nights and she stays put in there throughout the night. It's good and bad because she's a hunter and now she's doing less hunting and more sleeping, but at least she's warm and happy.
