One of our cats got sap all over her paw, so my wife was bathing her to get it off. She was kneeling in front of the bath, holding the squalling cat, when our other cat came into the bathroom. He first stood on the rim and checked to see that we weren’t killing her. Then he went behind my wife and started patting at her, I guess trying to make sure that everyone was ok.
Basically it was one of the most adorable things I’ve ever seen.
