Why Does My Cat Chatter at Birds?
The short answer
That rapid teeth-chattering at birds is a mix of hunting excitement and frustration at not being able to reach the prey. Some experts think it may even mimic a bird or prey’s sound. It’s a normal, instinct-driven behavior.
The window-side chatter is one of the most entertaining cat behaviors — and it’s driven by deep predatory instinct.
