Meggie the Maine Coon taught herself to go pee in the toilet!! We have recently heard running water or sometime going pee when we knew no one else was in the house. We didn’t think much of it, but then we started noticing that Meggie would walk out of the bathroom that we heard the noises in, and didn’t believe it could actually be her. We finally caught her in the act! We never taught her this and have no idea how sometime teaches their cat to use a toilet. She must have just learned from seeing her humans do it. She’s a super smart cat!
