Thank you so much for your contact, PetLink. Because of the microchip we were able to bring our cat, Charlie, home after one year and four and a half months. Charlie was found in a city 17 miles from where we live. He was so thirsty and hungry when he came home and after eating and drinking he had to tour every room in the house. He is snuggling with my daughter and myself, and when he is with one of us but hears the other, he comes running. He loves his peeps and is happy to be back with us. Thank you, PetLink!
