Questão Can you use NPC animal avatars?

Is it possible to use NPC animal avatars with the farm? For instance - a horse.

It certainly is possible and in fact there is now an NPC horse and cart you can pick up in the outside area of the Mintor store. I have recently started looking in to the possibilities of using more NPC's, but I am also aware that the current NPC farmer system is really in need of some major re-work, as it is quite limited and also it seems to work well for some but not at all for others.

Thanks. I can't even imagine the amount of work involved. My thought / question was around NPC being able to behave like the existing animals - eat, drink, move around, etc. Likely not worth the effort but was curious if it had been done. Thanks again!
