While this isn't true for me, I do feel disappointed when someone doesn't like cats, like I am sure dog lovers do with people who don't like dogs. I am a cat lover for sure. But there are definitely asshole/difficult cats out there.
As this also doesn't hold true for me, I thought it was funny because I am sure there are many out there that feel this way! I do love my in laws though, and I am glad I do.
