What Is Chattering in Cats?

Chattering is a fascinating vocal behavior exhibited by cats. It is characterized by a rapid stuttering or clicking of the teeth, accompanied by a shuddering of the jaw. Often, cats emit short, soft, or high-pitched tweets and chirps while chattering. This behavior is commonly observed when cats spot a prey animal, such as a bird or a rodent, outside a window. Chattering is a series of quick and rhythmic jaw movements, giving the impression that the cat’s teeth are clicking together. It is considered an unvoiced vocalization, as cats are not actively using their voices. Instead, tension is held in their mouths, resulting in a low-amplitude jaw sound. Chattering is classified as a solicitation call, along with chirps, tweets, and meows, which cats use to communicate with humans when they are excited and want something.

Expression of Hunting Instinct

Cats most commonly chatter when they have spotted a prey animal, such as a bird or a rodent. When your indoor cat chatters at a window or door, it’s likely because they have seen a bird in a nearby tree. While the exact reasons for chattering are not fully understood, there are several possible explanations. Chattering may express a cat’s excitement about seeing prey and may even be a manifestation of frustration at not being able to reach the prey. It could also be a way for cats to communicate their desire for the prey, especially when it is unattainable. Additionally, chattering and chirping may serve as a form of mimicry, enabling cats to imitate the calls of birds and rodents. By fooling their prey into thinking they are harmless, cats can get closer and increase their chances of a successful pounce. This hunting strategy has been observed in wild cats, such as the ocelot, which mimics the cries of baby monkeys to draw curious monkeys closer before attacking.

Signs of Chattering in Cats

When cats chatter at birds, they display intense focus. You may notice their eyes widening and their ears moving forward. They may also make small movements toward the window in the direction of the bird. Their jaws will move rapidly up and down, causing their teeth to click together, and they may produce high-pitched or soft gasping sounds. Cats become fully absorbed in the act of chattering and may express annoyance if interrupted. Once the stimulus that triggered the chattering is gone or if they find something else of interest, cats will naturally stop chattering.

No Need to Worry

Chattering in cats is a normal behavior, and there is no need to worry about it. It is important not to reprimand or interrupt your cat when they are chattering.

By offering various activities and daily challenges, you can help mitigate any frustration your cat may feel and improve their overall health.

Creating Stimulation and Entertainment

To provide stimulation and entertainment for your cat, consider the following options:

Multiple Levels for Climbing

Providing multiple levels for climbing, such as shelves and cat trees, is crucial for your cat’s well-being. Cats enjoy perching at different heights, allowing them to observe their surroundings and satisfy their instinctual need to be in elevated positions.

Scratching Opportunities

Offer opportunities for your cat to scratch and flex their claws by providing scratching posts or boards. Scratching is a natural behavior that helps cats maintain healthy claws and mark their territory.

Overall Health Improvement

By ensuring your cat has ample stimulation and entertainment, you can help improve their overall health. Physical activity and mental stimulation prevent boredom and promote a happy, well-rounded feline.
