Health officials in the East Bay say a cat with rabies was euthanized in what they described as a rare case. According to the initial findings, the animal was an indoor-only cat but may have been exposed to the virus after contact with a bat on an outdoor balcony.

Authorities said the suspected source of exposure was a bat rather than another pet or wild animal commonly encountered on the ground. That detail stands out because the cat reportedly lived indoors, suggesting the risk may have come from a brief encounter in a space connected to the home.

Vector Control staff inspected the area for signs that bats were roosting nearby, but officials said they did not find evidence of a bat colony at the location. Even without signs of roosting, the investigation indicates a bat may still have had contact with the cat.

The case underscores how rabies exposure can happen in unexpected ways, including for pets that are largely kept inside. Officials are treating the incident as unusual, with the available information pointing to balcony bat contact as the most likely explanation.
