I haven't hung around places like or 4chan enough to hear any of these creep's fantasies but this does remind me of a story I was working on a while ago with a similar premise

Basically my idea was that there would be a facility where the catgirls are produced and while those born male are rare and often killed at birth the protagonist would have survived to adolescence by being protected by the others until he eventually escapes and grows up to go on a rampage of revenge with the goal of liberating his fellow catpeople and making those responsible for their suffering pay

I should go back to that idea, definitely something there
