I have a lot of cute pictures of my two kitties sleeping together. My Siamese---14 pounds climbs into the cat bed with my little Chianti---5 pounds and makes her move over for him so he can snuggle and get warn. I have two cat beds next to each other but he insists on getting in with her for awhile. The sleep like this for a few hours then separate. Simon likes to do it more than Chianti does. She never climbs in with him but he is bigger and makes her cuddle up for awhile. He's a bigger baby than she is. LOL
