Does your cat seem to 'change' up their habits? I have one that seems to pick different spots to 'sleep' in. Just when you think that is her favorite spot, she will up and pick another one. I guess their moods change.
I know just what you're talking about. We have one that is kind of like that too. He will sleep in this one area for weeks at a time, then all of sudden he finds another place. It's like he has to try out all the places in the house. Cats are weird characters.
My cats seem to have many "favorite spots" to sleep. I don't think they change their habits, I think they like the sun. Where ever the sun is shining in the house is usually where you will find them sleeping.
