Zoo Med Hanging Mealworm Feeder: Mealworm Feeder #TA-22 Zoo Med Hanging Mealworm Feeder adds excitement to your reptile's feeding time. Give your reptile the joy of hunting these worms from the hanging feeder, as worms slowly fall from holes in the cup while your pet watches in excitement. This provides a more enjoyable experience for your pet, as opposed to dumping food directly on the dish.
