Cats are the death of fortress. Dwarf fortress is an incredible game but you are right that it’s actually amusing the amount of weird things you know you should avoid or manage as a regular player.
Bah, put the kittens in a cage and release them upon unexpecting intruders. 50-60 kittens will tear a Kobold apart if you lock them all into a small room.
For the un-initiated: Yes, Dwarf Fortress is a brutal game.
