Features:

Built-in timer, no battery or charge! 
When the timer is unfolded, the holes are arranged from small to large, revealing what is inside. 
When the hole on the toy is aligned, the snack can only fall off, so your dog is still fascinated. 
The game time can be as short as 5 minutes or as long as 45 minutes. Up to you! 
It is recommended for small and medium dogs.
