USB Rechargeable Vibrating Cat Chew Toy

This chew toy is shaped like a round little creature with a spiky belly and small fins, so a cat has lots of nubs to grab with its mouth and paws. The body is made from TPR, a soft, flexible material that gives a little when bitten, and the toy is sold as a gnawing toy.

It is electric, with a large-capacity battery that charges over USB, so there is no need to buy batteries. The toy weighs about 3.9 ounces (110 grams), which is enough heft for a cat to push it across the floor but light enough for a kitten to carry.

It comes in green, blue or yellow, and all three share the same shape and weight. The smooth lower half and the studded top give two different textures to explore.

Supervise play, especially the first few times, and check the toy for chips or cracks before each use. Put it away to charge once the battery runs low. To clean it, wipe the TPR body with a damp cloth and let it dry, and keep the charging port dry.
