The lucky mare didn’t experience your plight, in fact you doubt she even felt the cold. Your hand, which had been resting on her in your sleep, gently feels the dense fur of her upper foreleg. It’s not nearly as thin and short as the hair on a horse’s hide, if anything it has more in common with rabbit fur. It’s just like a coat…a jacket for high altitude flying. The plush fuzz fills your fingers as you close your eyes and search for a reason not to go back to sleep. Dash’s coat was the only one you’d ever felt, but you’d bet that pegasi had the thickest of the three genres of pony.
