Eh, just comes across to me like it was sleeping cozily moments before the picture was taken.

The fluffed up fur on the back makes me think the cat might be in some pain/discomfort. We had a cat with FORL who had severe tooth pain, she often looked like that when she wasn’t feeling well. Cats are really good at hiding pain so it took us a while to understand.

This cat might be just fine though, I don’t know the context of the picture.
