Let me know if what I am going to say coincides with what you, feline guardians, have been feeling, that cats are the most illogical and unpredictable pets. In fact, you can’t work out what is going through that little furry head, right?

Needless to say, you and your feline friend don’t share the same language, but it’s totally possible to find a common one between the two. And this is the key to mutual understanding in the long run.

As a result, it is your job to try hard to translate your friend’s behavior into actual words and then react quickly in return. Among the most commonly found bizarre things cats do is chattering at their prey. Are you curious about how this actually works? Keep on reading!

What’s going on around that makes cat chatter?

Are you familiar with the scene of your cat staring out of the window doing the little clicky things like mumbling some nothings to himself while keeping intense eyes on the approaching birds?

Probably yes. This is when the cat becomes riveted to the bird, and might want to hunt it. You may know this moment when seeing your felines chattering their jaws repeatedly, flicking their tails back and forth, at the same time performing the clinking in sync.

So why do cats chatter when they see birds? And do they do the same thing at other prey?

Why do cats chatter?

Predator instincts

The hint lies in feline mouth anatomy.

Cats have a special Vomeronasal organ located in the roof of their mouth which works similarly to a scent analyzer. Thanks to this sensory “tool,” cats can pick up the smell around them, and be sensitive when hunting.

The organ contains two different areas that allow air to come through them. When cats chatter, they are moving air across the glands to have a better sense of the approaching preys.

The deeply-rooted predator instincts are activated when the cat spots his prey flitting about or resting temporarily on the ground. He then makes the chattering noise as a tactic to lure the miserable birds into his hunting territory.

The scary vibration from his jaw is known as the “fatal bite” which occurs when the cat leaps upon its prey and grabs its body tightly with his claws. Then, he quickly bites into the back of its neck and rapidly vibrates his jaw so that his teeth slide into the vertebrae and across the spinal cord. How brutal!

The explanation also helps uncovers the question “Why do cats chatter their teeth?”. Strangely, the chattering may seem funny and adorable but what is behind it is an unimaginably dreadful vision.


Why do cats chatter when they see a bird? The answer is more simple than you may think. That’s because the feline friend gets irritated about being unable to get the prey which appears to be “too close, yet so far.”

The desire to showcase the skillful techniques of a hunter is so hard-wired into a cat’s mind that he can’t overcome the overwhelming frustration of the fact that the bird or bug in sight is unreachable.


Forget the obsessive scene of their hunting, the distinctive sounds of cat chirping might have something to do with excitement instead. Cats are indeed funny and passionate creatures. They love befriending other breeds of animals, including ones they normally prey on.

I am not defending a cat but perhaps those expressions like chattering, or vibrating the jaw are just signs to show a sort of exhilaration or eagerness to see a little feathered friend nearby. Likewise, cats react similarly at the notice of a bug and so on.


Scientists have witnessed cats trying to mimic the cries of monkeys in the wild; thus it is reasonable to infer that it’s likely cats will do the same thing to birds, and many other of their favorite “snacks.” But what is the point in doing so? Do cats want to entertain their friends? Or do they attempt to express some special feelings?

Neither is true. Your cunning little feline is creating a false impression of himself as a friendly partner to give the poor bird a sense of security and connection to “relative species.” When the prey is placed in a vulnerable situation, Mr. cat will uncover the mask and deal with the “victim” in no time.

Why do cats chatter at humans?

Cats chatter at birds partly because they want to hunt them. But cats chatter at humans, not because they want to attack their owners. Such a relief!

In fact, when cats are making that special sound at you, they might be in a confusing situation, and you have accidentally done something to add fuel to the fire, causing them great annoyance or anger.

For example, the last staw will strike if you keep on bothering your cat when it is slightly sniffed or excited about something.

In other cases, some will ask “Why do cats chatter when I sneeze”? Because your cat feels that things are getting out of control and that he is unable to stop it from happening. In this situation, tell him “Don’t cut off your nose to spite your face” in case he takes it all out on you.

What to do when you cats chatter

If you cat chatter because he is frustrated, try pleasing him with a variety of toys such as lasers, balls, feather chasers, etc anything that can make him forget his fleeing prey, and change his mood.

Or if your cat chatter about being too excited when spotting a bird, be quick to satisfy his excitement by inviting him to a playground or introducing him to some fun games.

Things to consider

Even though chattering is deemed to be innocuous to your cat, you should monitor its behavior in case it is doing this chattering its teeth too often. This may be a warning sign of looming diseases. Give the cat a check-up if you notice anything wrong.

Final words

Cat chattering is an interesting sight to behold until you get to discover the reason behind it. But that’s the cat – an animal which expresses their feelings crazily or uniquely to converse with the living things around. They are special also because of such odd behaviors. Finally, it is your job to sympathize with them and make a thoughtful response to their peculiarities.
