[Interactive and Interesting] There are two ball rotations and a funny cat stick on the track, which can effectively attract the cat's attention. The 360 rotating design of the tumbler brings more fun to the cat. [Adjustable Food Distribution] Different from other cat toys on the market, we can adjust the size of the two food distribution holes as needed to control the pet's eating speed. [Safe and Durable Material] The upper and lower parts of the tumbler toy are made of PP, which is environmentally friendly and easy to clean; the transparent PC material in the middle allows the cat to see the snacks inside and attract the cat to come. [Easy Operation and Convenience] Open the lid and put in snacks, adjust the dial inside, you can choose 1 hole or 2 holes to leak food, and it is also possible to turn off the function of leaking food. Through the cat playing with it, the toy begins to leak food. [Intimate Tips] The maximum diameter of the food distribution hole can be adjusted to 2cm, and the added food should be smaller than this diameter, or the food can be cut into smaller pieces and put in. Please put dry granular food instead of sticky food.
