Well, there's this shelf (supposed to be for phones, I think) on the corner of my desk. TV, Cosy, Autumn, and Domino believe that that corner is actually for them.
Cosy's other favorite spot is on top of the tall book case.
TV and Domino also favor the back of the couch.
Leo likes the half pipe on the cat tree (curved open shelf).
I have another S-shaped thing that is supposed to be used for scratching (it is horizontal). Jemmy says that he feels like he is a king in it.
Ozzy's favorite spot is right here. He jumps up on my lap every morning and snuggles in while I have coffee.
Mowie hasn't lived with us long enough to pick out a favorite spot yet but she's liking this spot on the grandkids' toy shelf, hanging out with the other cool cats.
