If you have a cat or dog that's prone to wandering, the G-Paws Pet GPS tracker might be worth considering. This weatherproof tracker can clip on to your pet's collar, and when they return from their travels, you can download the information to see exactly where they've been. This is more for your own interest; it won't track your pet live (which would be more useful), but it may provide a vital clue or two the next time they go AWOL. It records location every five seconds, and will last for about eight hours, and the data can be viewed and shared via Google maps.
