Shiatsu with Horses Book

An interesting if somewhat neglected book from my library. I thought it was fascinating that animal tool users are most likely female, and it appears altruistic communicators are also likely female. (does this mean females are smarter and kinder?) :) I thought the descriptions of the scientific method used in the experiments was also interesting, but wondered about the lives of the animals after the experiments were over and they were no longer surrounded by their surrogate human families.
