When dogs have no fur, they freak out. Wanna know why? Because now they can feel the air hitting their skin, they can feel things they haven't on their skin before, it was most likely running because it was cold, and I have no idea about hitting it's head but quite frankly laughing at that is rather mean. WE <3 ANIMALS HERE, ESPECIALLY CATBOYS.
Catboy's not an animal, he's too humanoid.
What I find funny is when my fennec RL tries to headbutt itself through a wall though. IT just stands in front of it, repeatadly (and slowly) moving it's head on and off the wall, like when a person hits itself in the head when they're trying to remember something.
