Here is a cute robot mouse with obstacle avoidance that moves around to keep your kitties active. The Pixie from PetLibro has two smooth wheels and works well on tiles, wood, marble, and other hard surfaces. It has a rechargeable battery and lasts up to 160 minutes. It rests every 10 minutes, so your kitties won’t be overstimulated.
With unpredictable movement, Pixie keeps your kittens on their toes. It is made of non-toxic materials.
