This is a great new product - we all know how fascinated cats are by bugs and flying creatures. Powered by a small fan, these bugs come alive and circulate around and around inside the jar! Bug Jar is specially-weighted and designed on a rocking base, allowing kitty to swat and play endlessly without tipping the jar over. An added feature for the cat that never sleeps, bugs can be charged under a light to GLOW-in-the-dark. Requires four AA batteries (not included).
