Amazon.com: Tractive Waterproof GPS Cat Tracker - Location & Activity, Unlimited Range & Works with Any Collar (Dark Blue) (TRAMINDB) : Pet Supplies

I like to see where my little man goes all day, the wifi power-saving feature is great because most of the time he's close enough to where it doesn't need to use the GPS so the battery lasts pretty long. It's pretty accurate, especially with the Live feature.
