Why Do Cats Chatter at Birds?
Cats are known for their diverse and entertaining vocalizations, with chattering being one of the most intriguing. This behavior involves rapid teeth clicking and jaw shuddering, often accompanied by short, soft, or high-pitched tweets and chirps. Cats typically chatter when observing prey animals, like birds or rodents, from a window.
What Is Chattering in Cats?
Chattering consists of rapid, rhythmic jaw movements that give the impression of teeth clicking together. It's an unvoiced sound, meaning cats aren't actively using their vocal cords, resulting in a low-amplitude jaw sound with tension in the mouth. Chattering is often accompanied by chirps and tweets.1
Chattering is considered a solicitation call, similar to chirps, tweets, and meows when cats communicate with humans. These calls indicate excitement or a desire for interaction or something specific.1
Cats demonstrate impressive flexibility in their vocal behaviors, with up to 21 distinct vocalizations documented. Chattering is one of these communication strategies, reflecting a cat's hunting instincts and attraction to prey animals like birds and rodents.1
Why Do Cats Chatter at Birds?
Cats typically chatter when they spot a prey animal, such as a bird or rodent. This is why you might observe your indoor cat chattering while looking through a window at a bird perched in a nearby tree.
While the exact reason for cat chattering is uncertain, several theories exist. Chattering might display excitement upon seeing prey or express frustration at being unable to catch it. It could also be a way to communicate their desire for the unattainable prey.1
Chattering and chirping might serve as mimicry, a hunting strategy. Cats could imitate the calls of birds and rodents to trick their prey into believing they pose no threat, allowing the cats to get closer for an effective pounce.
Cats in the wild have been observed using this mimicking strategy. For instance, an ocelot was seen imitating the cries of a baby monkey, attracting curious monkeys closer until they realized their mistake and fled.2
Signs of Chattering in Cats
When cats chatter at birds, they often exhibit intense focus. You may observe their eyes widen and their ears move forward, and they may also make small movements toward the window in the direction of the bird. Their jaws will move rapidly up and down, their teeth may click together, and they may make high-pitched or soft gasping sounds.
They will not want to be distracted when chattering and may express annoyance if interrupted. Cats will stop chattering on their own, once the stimulus is gone or they find something else that holds their interest.
Next Steps
Chattering in cats is a normal behavior and there’s no need to worry about it. Cats should never be reprimanded for chattering, nor should the behavior be interrupted or stopped. However, because chattering may be associated with frustration at not being able to hunt prey, like birds, in a natural setting, make sure your indoor cat has plenty of stimulation and entertainment.
Challenges like puzzle toys that hide food or treats can help your cat express natural hunting instincts and promote problem-solving abilities. Providing multiple levels for climbing, like shelves and cat trees, is also important for your cat’s well-being, as well as offering opportunities to scratch and flex claws through the use of scratching posts.
While there's no need to worry about a cat chattering, providing them with ample activities and daily challenges can help reduce any potential frustration and improve overall health.
