Pet Qwerks® Animal Sound Babble Balls® are fun and interesting dog toys that appeal to your playful pup's animal instincts with wild animal sounds. As your pet breathes on it or walks past it, the animal sounds ensue, 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 that range from exotic animals like lions and elephants to your everyday animal 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.
