Vegetable tanned leather, pony beads and pacifiers. Birds love to chew the leather, and most birds find the pacifiers irresistible. Good for small birds and any bird that just doesn�t seem to like to play with toys. A woman who runs a local bird rescue swears by them. She has had many birds come in that don�t know what to do with a toy. She puts one of these in, and eventually they will begin playing with the beads and pacifiers.
