Many cat owners like to get close to kittens, but the arrogant cats refuse to humans who have no sense of boundaries and want to touch their hands as soon as they come up.
Why is it so difficult to shake hands with cat stars?
In fact, unlike loyal dogs, humans have never completely domesticated cats.
Like many cats, cats are born lonely hunters. Most domestic cats still retain their original wildness. The hunting and scavenging skills are still sharp, and they can easily survive independently of humans.
So, in the eyes of cats, they have never been anyone's pets. As a solitary predator, it is normal to have a bit of arrogance and coldness.
Especially what you want to touch is their delicate claws. For cats, these four claws are magical tools that have evolved from walking in the world for many years, and it is even more reasonable not to let you touch them.
This pair of claw pads consists of three layers of precision structure, and professional sneakers are willing to give in.
The outermost layer is the skin layer, which is the part that is in direct contact with the ground. This sole is made of the toughest material, responsible for directly bearing friction and impact during movement, and full of anti-wear properties.
The second layer is called the dermis, which is rich in elastic fibers and collagen fibers, and can withstand very strong pressure. The dermal nipple composed of matrix tissue intertwines with the epidermis to form a honeycomb-like structure that helps absorb impact forces during impact. This middle layer is like an air cushion on the sole, with a very good shock absorption effect. The third layer, known as the subcutaneous layer, is mainly composed of adipose tissue and is the most important energy absorbing layer in the claw pad. As the innermost and softest layer of the three layers, it is equivalent to adding a thick layer of padding to the flat shoes, allowing cats to enjoy the pleasure of "stepping on shit".
It is precisely with this set of powerful claw pads that cats can fly around the eaves and walls freely, and jump to 4.5 times the height of their body length.
The metacarpal pads in the center of the cat's front paws and the two toe pads on the outside bear the main impact force when landing. The functions of cat's claws are far more than these. In addition to the shock absorption function, more importantly, cats can sense the surrounding environment through them.
The cat's claw pads are densely distributed with a variety of receptors [5]. These receptors can transmit various stimuli in the environment to the brain, allowing cats to detect various information around them with their paws alone. The skin sensory feedback of the claw pad plays an important role in regulating body balance, especially in less flat fields such as ladders or slopes, where the loss of skin sensation will significantly affect balance control. In actual measurement, when the receptors of one claw pad are paralyzed by the drug, the center of gravity of the cat will unconsciously shift to the anesthetized side during walking.
Inside the cat's claw, there is also a receptor called Pasini small body. It is sensitive to vibrations of 200-400Hz, giving the cat the ability to detect ground vibration with its claws.
These receptors receive various information in the environment and cooperate with each other, greatly enhancing the cat's perception of the surrounding environment.
Especially in perceiving the speed of movement and direction of movement, the claws have the most obvious increase in cats. It is not an exaggeration to say that they are the extra open sky eyes of cats. After all, the position of the cat's brain that processes the tactile information of the claws is located in the same place as the visual information of the eye.
Not only that, cat claws can also detect temperature differences keenly, and their sensitivity to temperature is no worse than that of human palms. They can identify temperature differences that are only 1°C apart. When encountering high temperatures, as the only part of the cat's body equipped with exocrine sweat glands, the claw pad can also dissipate heat.
Cats can also take away some heat by evaporating them through evaporation. Therefore, this magical tool is of great significance to cats. It can fly over the eaves and walls on the top and insights from the bottom. For those who are not familiar with them, the hands of the arrogant cats cannot be pulled just by just wanting them.
In order to shake hands with the kitten as soon as possible, you can open more cans and establish a good relationship with the cat. Maybe one day the kitten will allow all poop shovelers to pinch their precious claws.
