Why do cats have mustache?

Cats have whiskers, not mustaches. They are called vibrissae, and they are actually highly sensitive sensory organs.

Here's why cats have whiskers:

* Navigation: Whiskers help cats navigate in the dark and tight spaces. They act like "feelers" that detect changes in air pressure and movement.

* Predator and Prey Detection: Whiskers are incredibly sensitive to vibrations and air currents, helping cats detect prey and avoid predators.

* Measuring Spaces: Whiskers can help cats determine if they can fit through a space, like a small opening or a tunnel.

* Communication: Whiskers can also be used to communicate with other cats. For example, a cat might flatten its whiskers against its face to show aggression or fear.

In addition to these functions, whiskers also provide cats with a sense of balance and help them judge distances.

So, while they might look like a cute facial feature, cat whiskers are actually essential for survival!
