I hope your sick pony will eat and recover. You are doing your best and giving her love, too, I am sure. I took care of a lady, once, whose family owned a ranch. They would talk about how a horse can sometimes "twist a gut" and that could happen just from the horse just rolling around a bit on the ground. They explained that would be a big emergency. And I thought how there is so much more to caring for horses than I would have thought. I hope things get better for your horse, soon.
