An important reminder for cat owners and cats is that Rabies is a human health concern, NOT just an animal health concern. All pets should be immunized for this fatal disease. For cats that never really go outside, the risk is low but NOT zero. The Virginia Sate Veterinary Epidemiologist, Dr. Darby, relayed that it is not uncommon for bats to get into homes. These have the potential to carry and spread the deadly Rabies virus, and, she adds, that almost daily there is one that tests positive for Rabies.
