He was left at a vet's office. They had him for a couple of weeks, but when he tested FIV+, they said he had to go to rescue. So now he is safe with our rescue. Mom saw him on Saturday morning and kitten-napped him. He is maybe 7 weeks old, so he will hang around here for a while and we will have him retested (not that it matters - if the 2nd test comes back positive he will still be available for adoption).
