My version of cat mom would be simply, a woman who has more then one cat minimum 2 and treats her cats as kids, or joke about them as being the same as having kids, maybe also emotionally favouring to investing in them: Lets playfully saying, someone tries to talk to me but i have my alone time with my cats. Is that what you were looking for a response for?
priority cats over humans. ok. i have cats, they deal with rats really well in the farms and around the houses. they sleep with the dogs and eat from the same bins. the joke is about the cats being just another dog that can climb.
i have seen old people both men and women that will priority pets over humans. probably due to things going poorly with humans...
i would think if the girl is young and priority cats over humans she likely had poor relations with humans. cause of that is many things...
i don't see men do this often, it happens but not as common.
women live in the social wavelengths more. if that is broken it affects them more. many men can deal with it and simply isolate or stoic and be fine or hide it better.
i would not immediately discard due to couple cats. its common to get 2 so they can play together. 5+, that's getting extreme...
