Note that the obvious strategy of not having any cats at all doesn't work well because cats are the most/only easily-available HUNTS_VERMIN creature, so you need some around to protect your food stockpiles.

A somewhat effective solution is to use male cats for stockpile protection, and keep female cats caged (which IIRC stops both adoption and breeding) and only let one out at time (cage any resulting (female) kittens immediately). There's not (yet) any simulation of evolutionary pressure to adopt a owner quickly, so you can just prefer kittens that do so for the next breeder when the current one dies of old age.

Gelding (neutering) the male cats also works, but is less sustainable if you don't have a reliable source of replacement cats from migrants or trade caravans for when the current ones die of old age. Spaying is not supported AFAIK.

You can also just remove the ADOPTS_OWNER token via raws editing.

I. M.> John, the kind of control you're attempting simply is… it's not possible. If there is one thing the history of evolution has taught us it's that life will not be contained. Life breaks free, it expands to new territories and crashes through barriers, painfully, maybe even dangerously, but, uh… well, there it is.

H. W.> You're implying that a group composed entirely of female animals will… breed?

I. M.> No. I'm, I'm simply saying that life, uh… finds a way.
