Cats have always been good friends of human beings. Even if they don't do their jobs (don't catch mice), they won't reduce people's love for them. Recently, however, some people have been cruel to this cute pet. In order to use them as hairless cats for high profits, some ruthless businessmen shaved all their hair, even their beards. So, what's the sanctity of these hairless cats that cause common cats to suffer? Now follow 360 common sense net to understand!
A hairless cat is a cat born without hair. Its wrinkled skin makes it look more like a sanddog. The naked body is not only without aesthetic feeling, but also far away from our imagination. Although ugly in appearance, it's not easy for meow star people, who are famous for their loveliness, to grow up like this, because hairless cats are genetically determined.
Is a hairless cat really hairless?
To produce a hairless cat, first of all, both parents of the cat should have the recessive gene of hairless. Second, the gene is mutated when it is passed on to offspring. Only when the above two points are met can hairless cats be born. Because of the harsh conditions, the number of hairless cats is far less than that of hairy cats in nature. In addition, it is also found that there is no way to breed offspring between hairless cats. Only by crossing hairless cats with short hairless cats can we breed a small number of hairless cat offspring. Because of the scarcity, the value of the hairless cat is much higher than that of the ordinary cat, which is the scammer's motive to disguise the ordinary cat as the hairless cat.
The hairless cat has protruding eyes, thin cheeks and open ears. It can't be called "the ugliest cat in the world". However, its bald and ugly appearance doesn't affect its reputation. In Britain, the price of hairless cat has reached thousands of pounds. Hairless cats are so popular. In addition to satisfying people's curiosity, they also want to experience the fun of keeping cats by raising hairless cats.
But in fact, the hairless cat can't be the pet of cat hair allergy. On the one hand, hairless cats are not really hairless. Their ears, mouth, nose, tail and other parts have soft lanugo [Note 2]; on the other hand, people who are allergic to cat hair are not allergic to hair itself. What causes the allergy is a protein called FEL D1, which is secreted by the sebaceous glands of cats. The skin of hairless cats also secretes this protein. So, the hairless cat can not help the cat hair allergy to achieve the wishes of cat.
Therefore, we should regard the hairless cat as a kind of ordinary cat, do not have too strong desire for it, so that more ordinary cats can stay away from the risk of being shaved, and will not be cheated.
The hairless cat likes to lick its body and clean its hair frequently. After dinner, it will wipe its beard with its front paw, lick its anus with its tongue after urinating, and lick its hair with its tongue after being held. This is a little hairless cat in the removal of body odor and dirt. There are many rough little protuberances on the tongue of a hairless cat, which are tools for removing dirt. Hairless cat licks the coat with its tongue to stimulate the secretion of sebaceous gland, make the hair bright and smooth, not easy to be wet by water, and can lick a small amount of vitamin D, promote the normal development of bone, also make the coat fluffy, and promote the function of heat dissipation. The hairless cat usually after eating and playing, or after chasing after the prey, and after waking up in the sun, it starts to comb and tidy up its coat. In the hot season or after vigorous exercise, the body produces a lot of heat. In order to keep the body temperature constant, excess heat must be discharged from the body. Therefore, the hairless cat will use its tongue to smear saliva on the coat. The evaporation of water in saliva can take away heat and play a role in cooling and relieving summer heat. Combing frequently during depilation can promote the growth of new hairs. In addition, by catching and biting, the coat can be prevented from infecting parasitic diseases, such as flea and louse disease, so as to keep healthy.
The behavior of the hairless cat to cover up feces is completely out of instinct and is inherited by ancestors. The ancestor of the hairless cat, the wild hairless cat, in order to prevent natural enemies from discovering and tracking it from its fecal smell, they cover up the feces. This kind of behavior of modern hairless cat has no significance in this respect, but it has won a good reputation of speaking hygiene.
All cats have excellent day and night vision, so the Canadian hairless cat is no exception. The hairless cat still keeps the habit of nocturnal emergence in the daytime, and many activities (such as rat hunting, courtship and mating) are often carried out at night. The most active time of the day is in the dawn or evening, and most of the day is in the lazy rest or sleep. In the bright spot, the hairless cat will shrink the pupil as narrow as a line to reduce the damage to the retina, but will limit the wide field of vision. There is a layer of blue-green fluorescent film (called tapetum lucidum) on the back of the mesh of the hairless cat, which can increase the vision in the dark. In the flash, the hairless cat's eyes can present various colors. Like most carnivores, they have eyes straight in front of their faces, giving them a wide field of vision. The ability of hairless cat to recognize three primary colors is very poor. If Canada's hairless cats have only a small amount of light here, they will use beards to improve their mobility and perception. A very weak wind can be felt in the beard to identify the location of the obstruction when it is not visible. The hairless cat has three eyelids. When the eyelids of the hairless cat open, the blindfold will slightly cover the eyes from the side. If the hairless cat is ill, sleeping or laughing, the eyelid will retract part of it. If there is a hairless cat for a long time to show the third eyelid is a manifestation of illness.
Almost all the hairless cats usually have ears facing up. Unlike dogs, the hairless cats with ears folded down are very rare. The Scottish hairless cat with ears folded is an example of gene mutation. When angry or frightened, the hairless cat's ears droop, accompanied by a growl. When listening to things, the hairless cat will turn its ears, so that the hairless cat's ears can hear sounds from many sources.

Compared with other cats, they are sweaty and have a body temperature of 4 ℃ higher than the average cat, so they need to eat constantly to maintain their metabolism. This is a cat that is very sensitive to sunlight. Because there is no hair, the ability to adjust the outside temperature is poor, afraid of cold and heat, because the white part is easy to tan.
