KONG Bat-A-Bout Flicker Mouse will light up your cat’s playtime, day or night! This mouse’s motion-activated tail lights up and blinks when it is moved, batted, or swatted, luring cats into dynamic rounds of instinctual hunting action. Inner crackle material, KONG Premium North American Catnip, and various textures keep cats engaged, providing full-body exercise with each round of batting and flinging fun. The batteries included are replaceable to keep the fun ongoing.
