Tangential aside, which amused me to remember. My old-fashioned, rural (southern US) grandmother used to tell me to never trust a man who didn’t like cats, because he would dislike a woman for the same reasons. (Barring allergies)
That's a weird prejudice. I understand if it was about dogs, but there's plenty of reasons not to like cats.
There’s plenty of reasons not to like dogs as well.
Honestly, it's not even necessarily about not liking dogs. It's about "I'm OK with dogs but that means all our plans would have to fit into his having a dog." Nothing wrong with that, but implication of a lot more buy-in than with a cat generally.
Are there not plenty of reasons not to like women? (Also men but that's offtopic)
Ironically you're calling out a weird prejudice by showing your own weird prejudice
