I was sitting watching TV the other night & looked across to see our Australian Kelpie X (Maggie, who has to have a pillow under her head) fast asleep with our smaller than average cat (Bel, who is blind in one eye from a car hitting him 4yrs ago) wanting to keep warm on a very cool night curled up on top of Maggie fast asleep as well. I thought it was the cutest thing I'd seen them do for a while, Maggie tends to be more loving & caring toward Bel, I think she knows he's a little disabled & lets him do these things. Oh & yes they are sleeping on a full leather lounge (spoiled rotten pets). We have another cat (Baylee the Russian Blue) who is normal in the physical sense... he just has a "marking of territories problem around the house, even so he has been "done" he still feels the need to let all know he owns everything. When he is inside, he only gets to stay in the bathroom otherwise we couldn't have him inside at all.
