Thank you for viewing! This is a cat toy that uses LED light. Doggy Man / Catty Man A light beam in the shape of a mouse appears only while the button is pressed. If you move it in front of your cat, they will chase it. Unlike a cat wand, there's nothing to actually catch, which might cause stress. After playing with the light beam, letting your cat catch a cat wand seems to provide a sense of satisfaction. Please be careful not to shine the light beam into your cat's eyes.
