I found another interesting GPS tracking product for your pets. This one is a collar that allows you to track you pets movements from a smartphone. I think this one has an unlimited range (I think). If so, I am thinking about getting it.
There have been two instances where my littles one have gotten outside without me knowing. Accidents do happen no matter how much we try to protect them. Here's the link if anyone is interested. I just checked...it has unlimited range, you can track them anywhere in the US and it's only 79.00 but you get 15% for 67.99 if you use this coupon code FETCH-15. I am ordering one now
