Pet Qwerks® Animal Sound Babble Balls®are fun and interesting dog toys that appeal to your playful pup's animal instincts with wild sounds. The animal sounds ensue as your pet breathes on or walks past it, demanding playtime by enticing your dog. Animal Sound Babble Balls are available in three sizes and are made from high-impact ABS construction that can stand up to the toughest chewers, from your tiny teacup to your goliath Great Dane. Each ball makes more than 20 different animal sounds, ranging from exotic animals like lions and elephants to daily sounds like dogs barking, birds chirping, and cats meowing. When your dog is done playing, the Babble Ball turns itself off until the next swat or chomp.
