This is a versatile cat and dog toy that moves on its own. The self-weight design at the bottom of the toy ensures that it will not tip no matter how it shakes under the external force. This makes it a fun and exciting toy for pets to play with. The leaky food hole in front of and behind the product encourages the pet's interest in playing and improves their IQ. The playful interaction with the product causes the snacks to drop out of the food holes, which makes the pet more engaged and amused. Ultimately, this creates a fun learning experience that benefits the pet's development.
