We only had Lionel for two weeks before he made an escape. We were very worried because he was not familiar enough with his new home to make it back on our own and we were also worried because we live close to a busy road. he went missing Friday and by Monday afternoon we had been contacted by a local vet office. Someone had found him and brought him in. My children are happy to have him back and we are so glad that the PetLink microchip worked! Thanks so much PetLink!
