Tennis balls are big fun to fetch, but they can't hold a candle to the kick of nighttime retrieving with the Glowstreak Doggie Fetch Toy. Give it a toss and the motion-activated LED lights put on a multi-colored glow show as the tennis ball-sized toy streaks through space like a meteor. Made of tough rubber, it's impervious to slobber, even floats for water retrieves. 10-minute auto-shutoff prolongs the life of 2 replaceable lithium batteries (included) for up to 35 hours of nighttime play.
