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

I am going to suggest the answer to the first question is yes. If Cottage Living is an example of things, I have been able to have cows, chickens and Llamas in other worlds without problems. I'm also not one to arbitrarily have my Sims move into a new world just for the heck of it. I still have yet to even send my Sims to the new town that came with Growing Together. None of my Sims have ever lived in Copperdale, either. Eventually, I may explore those locations, but I'm still very much enjoying HoB.

As for werewovles' culinary delight in eating sheep? I have no clue.
