I bought some animals from a caravan because I thought "oh cool, animals!" but I don't really know what I can do with them. I guess the dwarves would like a bit of jaguar meat, but that seems a waste. I tried using my kennel to train wardogs (acording to the wiki, this will actually train other animals too) and train hunting dogs (ditto), but it told me there were no animals available.
So I tried moving the caged animals from the stockpile to somewhere else and tried again. Still no luck.
The animals were tame, so I tried releasing them from their cages and trying again. Still no luck.
Have I just been unlucky in buying, like, six animals none of which I can train, or am I doing it wrong?
[P.S. If I wanted to put animals that are roaming around the fortress back in cages, is there a way to be selective, or should I just put traps near my food supply and hope the right ones wander in...]
