We made the Push And Pull for birds with intermediate to advanced-level foraging skills. This bird toy creates a unique foraging experience. Birds can see the treats inside, but will it figure out how to retrieve them? Made of durable polycarbonate to stand up to active daily play, this mentally stimulating toy will engage birds for hours of rewarding fun. Simply fill the top chamber with treats, and watch your bird go to work by pushing and pulling the slats to release the food into the chamber below. The turn-lock top allows for easy refills. We recommend this toy for medium and large sized birds.
