YESYESYESYESYES!
In all seriousness, you should be able to domesticate any animal in-game, depending on personality or something. It would be cool to be able to get more animals over time insead of just one over the entire game. Of course, it's not like there aren't going to be any negatives to aving an animal in your party. Say, if you have a mountain lion as a temporary companion, NPCs natural responses might be fear or somethin. Or, if you have a rat and try to domesticate a dog, the dog might, through instinct, attack the rat, kill it, and eat it. Or, if you have a really aggresive animal, it might get angry to an approaching NPC and attack it. It will have to be put down then and there, and you would have to pay a fine for the assault that the animal wrought.
That would be cool. :wink_smile:
