The dogs and cats get all the attention from the volunteers, and the pigs and fowl get to do what they please. Some days it seems like our horses, mules and donkeys are second class citizens! (Well, sometimes people bring them apples . . . )
We found a few recipes for horse treats! Could you make some and bring them out? We don't know how long they will stay fresh, so don't make them more than a few days before coming out, and don't make a huge supply.
Most of the recipes here sound delicious (but we don't want the ones with peanut butter) : http://www.moniteausaddleclub.com/horse_treats.htm
