I had a female grey tabby Bella she would sit up on top of my chair when I was at the PC. Sometimes shed sit with her paws on my head and her chin on top of her paws all on top of my head guess it was cozy to her.
Of course I'd make her move as cat paws on top of your head cat stomach on your neck is not so cozy unless it is freezing cold. But she always tried that funny pose first.
That cat was sharp she could tell if I was in a slump and then she would near constantly be right beside me. Some say that animals do not have personality or empathy I strongly disagree. This cat was a stray I found.
