Made out of soft natural cotton, it is perfectly safe to put into your horse’s stall if he tends to get bored. The inside is filled with a plastic bottle that you can easily replace thanks to the Velcro closure. It produces a cracking plastic sound when you put pressure on the toy’s belly or head: make sure your horse will be intrigued and amused! The Relax Horse Toy should be hand washed – do not place it in the washing machine.
