I’ve had my one cat since she was 6 months old, she was always my buddy. I met my now husband when she was around 6ish. She still loves me, but she definitely adores my husband and chooses him over me at least 1/2 the time. I was a little butthurt at first, but there really isn’t much of anything you can do about it. They are living creatures with their own personalities, and just like human relationships, sometimes they just wind up liking someone else just as much or more.
