If you place your bat house according to instructions, occupants are unlikely to be caught by cats as it will be too high up for them. Dogs will have as much as interest in guano as they do any bird poop and are very unlikely to ever interact with a bat. We recommend that all your animals be vaccinated for rabies, as is common practice. If your house pet ever brings a bat into the house, call animal control to properly care for or safely dispose of the animal. Never handle the bat yourself.
