Cat chittering, also known as cat chattering, is a behavior that cats exhibit in response to prey, usually birds or small rodents. Chittering is a series of high-pitched, rapid clicking or chirping sounds made by the cat, usually along with an excited tail twitch.
Scientists believe that chittering is a hunting behavior that is triggered when a cat is excited and anticipating catching its prey. It is thought to be an instinctive behavior, as even domestic cats who have never hunted before can exhibit chittering when watching birds or other small animals through a window.
Some cat owners also report that their cats will chitter when they are particularly happy or excited, such as when greeting their owner or playing with a favorite toy. Cat chittering is a fascinating behavior that provides insight into the complex social and hunting behaviors of our feline friends.
