This is a very common question. Some indoor cats never leave the house, but many sneak out occasionally. That’s a chance for rabies exposure. Even those that never leave the confines of their house can be exposed to rabies virus from rabid bats. Bats are the carriers of rabies in Oregon. It happens far more often than people realize, even in apartment buildings in the middle of the city.
Vaccination is important to protect indoor cats against rabies, even if the risk of exposure is low. The MOST important reason is to keep your family safe from potential rabies exposure.
