Don't you understand cat logic, yet? It's not perched there because it wants to perch there... it's there so you can't be there.
I promise you I have never once tried to place myself on top of the headrest of that chair.
And really, I've never actually sat in that chair at all, since I got the cat. A second chair in here is now kind of... unused
So I put a blanket down on the seat cushion, and I think I've taken pictures of the cat on the blanket in the chair here before. That's basically
his chair. But naturally he found the least comfortable way to sit in his chair.
