I think mules are cool. My son has a friend that owns a small family farm, but since his kids are now grown, he has started to downsize with the animals. He still has his two mules, two pygmy goats, a pot belly pig that gets to stay indoors, two dogs and one cat. The one goat insists on bucking me, but I don't know why. The guy that owns the goats said that I am the only person he bucks. The pig, squeals as soon as I try to pet him. However, if I offer him food (carrots), then he is OK with me rubbing his head. Oh, he also has a really nice horse that he rescued from someone that was going to have her put down because her racing days were over. The outdoor animals are kept in a heated barn. The barn stays at about 60° and the stalls are kept very clean. I will have to get some pictures the next time that I go to his place.
