Animals have a way of doing that to us. But we love them so we do what we have to. I can remember back in the 70's, my ex's familly had horses. They just stuck them in the pasture and ignored them. No worming, no meds, no special feed and they seemed to do just fine. Once my daughter got horses I couldn't believe all the expense involved. Her favorite mare at one point got colic and never got over it. She took her to K-state. It ran up a several thousand $$ vet bill and her horse died anyway. I guess that is one reason I have never considered having a horse. I don't think I could stand loosing one if I got attached.
