Even indoor pets escape from time to time. Ensure you'll be able to track yours down with the Nuzzle GPS Pet Collar. This waterproof gadget works with your existing collar and uses a combination of GPS positioning and cellular connectivity to alert you should your furry friend wander outside a designated area. It also monitors the ambient temperature, letting you know if it's too hot or cold, and has impact detection, telling you immediately if they've been in an accident. Best of all, there's no monthly fee to worry about, which means more money for toys and treats.
