Hog Wild Cat Popper give a soft foam ball a big launch. Give the Cat Popper a squeeze and launch those foam balls out to 20 feet. The launching system is based on pressure so that the harder and faster you squeeze, the faster and farther the foam ball will fly. Six foam balls are included and can be carried in an included carry net. The foam balls are the perfect bright color and are easy to find. The cat popper works with all Power Popper refills.
