My Dr. Zoidberg used to do that. He would clean Isabel like that and then bite her at the end. I always wondered what that nonsense was about. It has to be dominance, right?
I think it's overstimulation. One of my cats does it, but he also bites if you pet him in one spot for too long, or just pet him too long in general. The other kitty will lay there all day if you pet him!
Jasper can get bitey when you pat him, I’ve always thought it was him being silly. He probably is trying to be dominant but Mishka sometimes gets her own back by ambushing him when he’s asleep!
