I met my neighbor last night as he was out looking for his cat. He said "I think she's been going further recently, I saw her up the street the other day." As we stood and talked the cat would come close, then run off again, repeating the pattern over again. I left him to scan the bushes with his flashlight, thinking he would almost certainly buy my cat-sized pet tracker. He could locate his cat when he needed to AND know for sure how far she roamed.
It also made me think about including a flashlight functionality... not sure how this would work, but it would be great if you could turn it on from your mobile device, illuminating the pet so you could spot them in the dark (and making them visible to traffic.)
