Yeah being homeless sucks, what does that have to do with cats reproducing?

Even if we assume that all unplanned kittens end up homeless, it’s still some twisted version of financial cat eugenics. “Your life will probably not adhere to my standards of what a good life is, so I will prevent you from existing in the first place for your own good. I will cut off your balls because your kids would be homeless.”

Now apply the same logic to humans. I know we are talking about cats but from a moral standpoint it should make no difference, the degree of “bad” might change, it’s less bad if you do that to an animal and more bad if you do that to a human, but in both cases it’s still bad. I can’t think of anything that this logic doesn’t apply to, even when it comes to something we do all the time like killing, if you do that to a human, that’s murder, which is obviously terrible and if yo do that to an animal, that’s acceptable, because we need it for food to survive but it’s still bad. If we could get meat any other way I don’t think anyone would be opposed to that.

If you don’t want to get castrated by aliens\AI overlords then don’t do that to your pets.
