Not always. I was at my sister’s house and her cat was not over-fond of me. That bothered me because cats normally adore me. At one point, the cat was half-snoozing on a stool so I reached over to give him a pet. At first he started to purr and stretched out. Yes! Thought I, finally making friends. Then he looked over his shoulder and saw it was me. He hissed and ran to the other side of the room and started cleaning himself. I’d have been hurt if his expression hadn’t been so funny when he realized that it wasn’t my sister petting him.
