I recently started played Dwarf Fortress, and not knowing that it wouldn't catch normal animals I caught some vermin from the Kennel. Now I have some rats and stuff sitting around in an animal trap on a stockpile, and I want to get rid of them either just be gone to free up space or release them to do something.(Maybe someone wants a pet rat/hedgehog/roach?) I've been trying to, but I just can't figure out how to. Can anyone tell me how?
To release the (now tame) animal use q to query the cage, a to assign, and then use enter to toggle the animal(s) currently inside (animals assigned to the cage will have a green
+ next to them). Any available dwarf will perform the job. (Source)
