A free rabies vaccination clinic for dogs, cats, and ferrets is being held at the Brookhaven Animal Shelter. The clinic is available to all county residents and vaccines are available while supplies last. The deadly rabies virus attacks the central nervous system and is often seen among wild animals, but any mammal can be infected with it. State and county laws require that all dogs and cats to be vaccinated against rabies. Vaccinating pets also acts as a barrier to prevent the virus from spreading between wild animals and people. The Suffolk County Department of Health Services recommends the following precautions to protect pets and humans from possible exposure to rabies: Don't feed, touch, or approach wild animals or stray cats.
