I have been wondering for some time if it is at all possible to convert any of these animals to neighborhood decoration, so they can be placed in locations where a lot can't be built. Especially those that typically are allowed to roam free (or once were) like the giraffe and American Bison. I've also been looking high and low for sheep, goats, rams, horses, as neighborhood deco to live on a mountain in my hood, so even regular animals would be great, not just exotic or zoo critters.
I have only been able to find some cows as neighborhood deco from rebecah @TSR. It gave me hope that I'd find others for my neighborhood, but I've come up empty. I hate filling my hood up with buildings and trees, so it would be wonderful to see animals roaming free like they once did, and still do in some areas - especially in my medieval hood.
