Health officials are warning residents Thursday to be alert after three wild animals tested positive for rabies.

Veterinarian Dr. Chuck Noonan says the number could hit four because he was recently forced to euthanize a squirrel after it bit a child. The squirrel has since been sent to Hartford to be tested for rabies.

Meantime, health and animal control officials warn residents that if their domestic pets come in contact with a wild animal they should be extremely careful. If they choose to examine the pet then they should wear gloves. Experts say rabies can be fatal to humans. Anyone who spots a wild animal on their property is urged to call Weston Animal Control at (203) 222-2642.
