I have registered with Feral Friends and the city for a trap neuter release group on Carnegie. If one of these is your cat I am doing my best to keep us from being overrun by stray cats who are also being eaten by natural predators. Just to let you know, cats I catch are taken to the veterinary hospital where I work and are tested for leukemia, Feline Immunodeficiency Virus, Rabies vaccinated and neutered or spayed. These cats are treated with care. I am doing this with my own money so if one of these is your cat, you just got over 150$ of veterinary care for free. They are not being taken to an assembly line spay neuter place.
