The Mesh Seed Catcher by Prevue Hendryx is a revolutionary creation that will prevent seeds from hitting the floor. It will collect seeds that may leave your pet's habitat and store them inside of this nylon mesh. The featured elastic band securely holds itself tight against the cage. It easily fits right around from the bottom base and up above the food/cup height. This Seed Catcher will fit 52" to 100" cages, raising about 13" high.
