Cats and dogs are responsible for many accidental parrot deaths each year. For this reason, parrots should never be left unattended around cats or dogs. Parrots are prey animals, while cats and dogs are natural predators, and even a gentle or well-trained pet can react instinctively.
Cats also carry Pasteurella bacteria in their mouths and on their claws. These bacteria are highly dangerous to parrots. Even a minor scratch or bite can lead to a serious infection. Because birds preen, bacteria can be ingested after contact, and symptoms may not appear immediately.
To keep parrots safe, they should always be housed and handled separately from cats and dogs, with close supervision whenever they are in the same space.
