I told my wife the cat favors her
How do you know your cat favors your wife?
I've checked with my cat on who she favors. She always goes to my wife, and it must be the yellow rose she gave the cat two days ago.
When married couples jointly own a cat, the cat can favor one spouse over the other, and this is normal. Just be sure your cat doesn't get jealous of you and cause you injuries.
I don't understand, how will it do that?
Well, just make sure that you also love the cat as how your wife loves her. Try to pet her whenever you can and play with her so that she wouldn't see you as a threat and also would feel calm whenever you are with the cat.
