This toy contains 3 2.2" fluffy plush balls. Vivid animal chirps when touched (frog/light blue, cricket/bright yellow and birdsong/ins pink). And the built-in batteries make each cat toy ball last 10,000 times of chirping.
The interactive cat toy balls for indoor cats come with an extra pack of fresh catnip which could be a great addition to making your cats playtime fun. If desired, open the lid and add catnip, it's super easy. Your cat will go crazy, increase activity and stay healthy.
Plush materials are soft and safe for your cats to bite, chew, and chase. These cat exercise balls are durable and resistant to drops and impacts.
Each ball has 2 LR41 batteries built-in. No sound when the ball is idle to save battery consumption. The battery is replaceable, but to prevent your cat from ingesting it, it will be laborious to open the battery cover. If you do need to replace the battery, follow the instruction to get it replaced.
