Found this today on Tumblr:
[Image description: Comment by tec63298 saying "The globalists are using cats to depopulate whites. Because cats act as surrogate babies they cause white women to not want to have kids. Cats are like a parasite that sucks the maternal instinct from white women."]
Quick note, "the globalists" is a class anti-semitic dogwhistle, so you know "whites" don't include Jewish people to this person.
As for the topic of cats sucking the will to reproduce out of white women, I mean, no, but if there's any chance at all that it's true, more cats for all my fellow white ladies.
