Can we add Goats to Tartosa and Sheep to Moonwood Mills?

I really hope the goats and sheep can wander a bit. If they can I will have them scattered around all over the place. I wonder if the foxes, cats, and dogs will interact with the goats, sheep and horses. I wonder if werewolves will annoy horses or the minis. I hope we can have horses in other worlds - it would be so disappointing if we can't. I have a silly vision of a horse in an apartment in san mushino. :D
