Why is my cat hissing for no reason?
When I pet him and he’s rubbing up against me, he will he purring and seemingly happy. Then he will just let out one lone hiss. But he doesn’t flatten his ears, raise his fur, or change his pupils. Then he goes back to purring like nothing happened. I’ve touched him all over to see if he has any pain spots but I haven’t found a specific spot that makes him hiss.
