This is probably going to sound strange, but I'm going to ask anyway. You probably won't get through reading this without laughing. Why do cats act so strange when you scratch the spot at the base of their tail? When I scratch my cats in that spot, their whole back end comes popping up in the air and their eyes start going shut and their head turns up and to the side and I swear it looks like they are smiling
! It looks like they are thinking "oh yeah! That's the spot." It must feel very, very good! But why do they respond that way?
