Here's how the cats are cleaned with each lick

A team of researchers have studied six species of doll languages ​​and reveals the existence of internal cavity in each papilla that collects saliva of the leaf and is distributed in the coat through the licenses.

Cat languages ​​have papillau that play an important part in the feline vesting work.

Domestic cats sleep on average 14 hours a day, but When they are awake, they spend up to a quarter of their time alleviating each other to remove flaws, the residues and replacement of the hair that covers your body. (Read: Cats are not good mice hunters, scientists say)

Their tongues are covered with hundreds of subjected edges with a curve at the same address of the name papillai, which is responsible for giving as much touch as that. According to a study published this week in the magazine National Sciences Academy, these fine structures include an empty shower at the front which plays a key role in feline architecture.

"It's been studied before the amount of the flea increases if cats do not clean and there were already microscopic studies of papillary. But it was not the first to find that the papilai had hole who participates in licking, "said researcher David Hu, co-author of this work to Zinc.

Each "U" shape cavity is responsible for collecting saliva from the mouth and then distributed by the hair in the licenses. In particular, all holes can store up to 4.1 μL of saliva, An amount matching one-tenth of the leak in the typical eye leak. In addition, with each lick, the spice deposits about 50% of the fluid in the coat to cool and regulate body temperature.

In this way, the relief tested by cats after marriage depends on whether the papillai can penetrate the fur to reach the skin. This explains why some species of domestic cats, comor Persian cats with long hair, they have a hard time warming them. (You can read: The first cat only in space is 55 years old)

"The papillai must reach the skin to dissolve the oil and the rest of the materials. The Persian cats have a coat too thick to penetrate the papilai. As they can not reach the skin, the cat can not be completely cleaned, "Hu added.

To reach these conclusions, researchers Alexis Noel and David Hu recorded rapid images of cats that interfere with each other and using a technique of computer tomography, as well as the power measurements of the lick, to understand the mechanism that hides behind each lick. They also analyze a different six-organ organ felines -Gato montés, puma, irbis, tiger and lion- and they rose after his death.

From the data obtained, the authors of the study designed a brush inspired by the cat's tongue. According to the researchers, this tool can be useful to eliminate cat fur allergens and apply for lottery and medicines on feline skin. Their curved pearls also allow easy hair cut, which is differentiated from traditional brushes. (Read also: New Zealand village will eliminate cats to protect their native seed)
