The GlowStreak Wild LED Ball is a fetching good time for your wild one. This rugged rubber ball features unique ridges that make for perfect gripping - whether in a hand, ball launcher, or muzzle. The ridges cause the ball to bounce in a wild new direction with each throw, keeping your pup engaged and focused for truly tiring play (so you can enjoy that post-play rest). The rubber shell encircles a protected inner core containing an innovative motion-activated module with color-changing Disc-O LEDs. The core also holds 2 easily replaceable, long-lasting CR2032 batteries for up to 35 hours of play. GlowStreak automatically shuts off after 10 minutes of inactivity to ensure the fun isn&&';;t wasted. Ideal for bigger breeds, this molded ball is shockproof, waterproof, bite-friendly, and slobber-resistant-it even floats for those fur-ocious swimmers.
