why do cats chatter

Cats chatter primarily as an expression of their hunting instinct, excitement, and frustration. This behavior often happens when a cat sees potential prey, such as birds or small animals, that they cannot reach. The chattering sound, which resembles chirps or rapid clicking of the jaws, may be a way for cats to release pent-up energy or practice hunting skills. It is also thought that the jaw movement mimics the bite cats would give to catch their prey. Additionally, some theories suggest cats may be trying to mimic the sounds of their prey or communicate excitement or desire to hunt with their human companions. This chattering behavior has evolutionary roots and is observed in both domestic and wild cats when observing prey.
