Perhaps I am alone in this, but my horses prefer to play with only the most expensive of items, eschewing all manner of horse appropriate toys in favor of things like blankets, full water troughs, and anything enticing within reach of their stalls. I’ve yet to see either touch the Jolly Ball or the little apple one with the treat. Jerks.
I doubt anyone in the history of riding has had to replace more Jolly Balls than blankets.
