I read somewhere about a year or so ago that cats don’t experience jealousy. I don’t remember the author but I do remember he had letters after his name so he was some kind of expert. I suppose if I was paying attention I would have noticed those letters to be “BS” because, even then, I knew he could not have possibly had cats. Cats can certainly be jealous. I know that because I live with Chris, who, if he was human, would be like the crazy ex-girlfriend who breaks into your house to go through your computer history (yes, that happened to me).
I know Chris is an extreme case but I see evidence of jealousy sometimes in our other cats. Floki, for example, will get mad at Chris if he is in the bedroom with Mom in the morning when Floki likes to get attention from her. If a new box is introduced, there can be fighting over who gets first dibs on getting inside. I don’t know if that is jealousy or its evil sibling, envy, but it’s so similar who’s counting.
Here is Chris while Frankie is on my lap. Can someone tell me that this is not jealousy?
