Cat whiskers don’t just look cool, they are the Swiss Army Knife of a cat…
They are the main sensory and communication source for your feline friend. Not only are whiskers your cats gps system, whiskers can also help them distinguish if they can fit through openings as their whiskers are generally as long as your cat is wide.
You should never trim a cat's whiskers either as they can become dizzy, disorientated and can show signs of confusion similar to that as a cars gps system shutting down.
As dogs tails show their mood and temperament, so too does your cats whiskers. For example, if the whiskers are sticking out side ways, they are calm. If they are pushed forward, they are excited or alert. If they are flattened against their cheeks, they are angry or scared.
Your cats whiskers are so important to their everyday activities, and the whiskers themselves are not like cats fur, they are rooted much deeper into the skin. Surrounding the whisker are more nerves and blood supply and interfering with cats whiskers can cause extreme sensitivity, even down to the size of they food bowl they eat from, i.e if their whiskers touch the sides of their eating / drinking bowls, it can be quiet disturbing and even painful for your cat.
Another interesting fact is not only does your cat have whiskers on their face - usually around 8-12 - they also have whiskers above their eyes, on their chin and the backs of their lower legs with these whiskers all considerably shorter than the facial ones.
Cat's also use their whiskers to hunt prey. They use whiskers on the back of their forelegs, as opposed to whiskers on their face or even their eyes, to sense the distance of prey, hence why you never see cats wearing glasses ;)
