We need to talk about cat languages ​​seriously.



New research reveals why the cat languages ​​are so rude.

Have you ever licked by a pussy? If so, the cat's tongue feels more like sandpaper than satin.

The language of a cat is covered with spines made of hundreds of sharp, scoop-shaped keratin that move during grooming. We don't really know why their language is so rude so far.

However, new research published this week in the National Academy of Sciences Proceedings Book shows that they play a role in helping a cat stay cool.

Cat Grooming

Domestic cats groom one-quarter of their waking time by grooming their fur jackets to help remove the awake cloaks and loose hairs. If it did not get tired, then any excessive rash could cool the fur, causing the skin to be painfully pulled out, or even to infection.

The new study, however, reports something else when a cat uses the language for grooming.

Scientists have used a cat tongue CT scan to study the structure of thorns known as papillae. The vertebrae are approximately 2 mm long and have a U-shaped cavity (then cause). The researchers also measured the hardness of the papillae and saw that they resembled human fingernails.

It was even more interesting when scientists used high-speed videography to learn what happened to the spines while a cat was taking care of it. Only the spines at the end of the tongue come into contact with the fur during inhalation. They are larger and are not as tightly packed as the spines near the base of the tongue.

As a cat groom, there are four steps. First, the tongue is extended orally. Then, the muscles in the tongue extend the surface and rotate so that the spines are perpendicular to the tongue.

In the last two steps, the tongue passes through the fur and is taken back into the mouth with a U-shaped crimp.

Using some fake furs and a force plate, scientists calculated that the tongue could actually contact the skin of the cat with the amount of compression on the fur.

The place where we need to think about cat saliva is even more interesting – and it also gets a little icky.

Saliva action

The U-shaped cavity at the end of the spines we have mentioned before acts as a wick in the mouth to take saliva. This is the same action when you put the tip of a tissue in water and the water surrounds the tissues.

Scientists, because they want to investigate the details of these spaces 290 spine about 4μL (microliters) have calculated that saliva. (It takes 1.200 times the amount of saliva to fill a teaspoon of 5 ml.)

This 4ırl is only 5% of the total saliva in the cat's tongue. Not so much, but the ability to store saliva on a cat's skin has a very important function.

Scientists used the estimate that cats spent about a quarter of their time awake (about 2.4 hours a day) and that they slept once per second.

This means that cats can lose a quarter of the total temperature they lose during the day by secreting tiny saliva from the tongue spines. (We're hot when we're hot.

Cool for cats

Most cats (not all) live in warm climates, which will be really important for their survival. The researchers looked at the languages ​​of various cats such as domestic cats, bobcat, puma, snow leopard, tiger and lion.

Most cats can effectively protect themselves by assisting them in their saliva and other enzymes (special chemicals).

Working by measuring how long the spine extends to the cat's fur and the length of fur in different races, scientists are the native Persians who often have long hair, working on single cats that cannot influence themselves for a long time.

This should take the time to brush them out if you have a Persian, otherwise forms can form and damage your skin and lead to infections. But scientists made another breakthrough here.

A new brush

In the last part of this research, scientists used the information they acquired about the spiny shape of a cat's tongue and used 3D printing to develop a better grooming brush for use in cats.

Scientists say that the biology-inspired brush helps cleanse allergens from cat furs and helps the application of any cleansing lotion and medicine on the skin of cats.

Brush design can also inspire news paths to clean other complex hairy surfaces.

Next time you watch a cat care, take a moment to see how great science is in the evolutionary design of its language.
