This is a patented product designed in an eggshell shape, crafted entirely from flexible, elastic material. The middle cavity can be filled with various treats, including dry kibble, wet food, treat sticks, freeze-dried snacks and peanut butter. It features a built-in slow-feeding column; as pets chew and play with the toy, they can gradually access the food inside. This design effectively slows down their eating pace and helps protect their gastrointestinal tract.
