Sure, you can microchip your pets and put tags on their collars, but the Whistle 3 GPS Pet Tracker is proactive about finding lost pets by notifying you when your furry friends leave designated safe spaces.

Using Wi-Fi and a cellular plan, the Whistle will pinpoint your pet’s location, similar to the Find My Phone app. I could see this helping ease a lot of anxiety, especially if your pet often gets out.

Today, the Whistle is down to just $50, which the least number of bones we’ve ever seen.
