Reunited Cat
I have to say I was very impressed with the scope of this service. I did receive calls from friends and neighbors that weren't aware that my cat was missing. I also received a call from my vet's office that they had been notified. I had been out of town at the time and this saved me a lot of time and provided me with some peace of mind to know that people were looking for him while I returned.
My cat came home on his own, but should he ever go missing again I would certainly use this service.
