Why are there only police dogs, no police cats?

“The eyes are like a brass bell, shooting a lightning-like spirit, the ears are like an antenna, listening to all suspicious sounds.” The black cat sheriff’s title song accompanied the country’s thousands of children after 80 years. In the story of just five episodes, the black cat sheriff slammed the hamster, captured the monkey eagle, and wisely ate the cat and mouse, becoming the incarnation of justice and courage in a generation.

However, unlike in cartoons, cats rarely play the role of a policeman in reality. It is also a favorite pet. Why is the dog already showing his talents in the police, but the cat is missing?

In 2016, a five-year-old British girl, Eliza, wrote to the police station that police stations should also have police cats. She believes that cats are good at discovering potential dangers, climbing trees and hunting, not getting lost, or even helping humans, so cats must also be good policemen.

How can I be a good policeman? A basic premise is to learn to obey orders. Therefore, animals that can be police officers are often highly domesticated.

Although some countries have used some special animals for military purposes, such as the US Marine Corps special training of bottlenose dolphins, California sea lions, etc., but from a worldwide perspective, the police recognized and large-scale application of animals Only police dogs and police horses.

The magic of time has definitely played an important role. Dogs and horses have been domesticated for thousands of years or even tens of thousands of years. Of course, getting along with humans is more reliable than other wild animals.

But the problem is that the cat owner is not too late to enter human life, although later than the dog, but far earlier than the horse.

About 15,000 years ago, a group of wolves discovered that humans would leave some food residue after hunting and camping. In exchange, these wolves also began to serve as human sentinels and guards. As time went by, these wolves gradually became early dogs.

Modern archaeology found that between 9500 years ago, there were people and cats buried in the tombs of Cyprus. People at that time began to grow crops such as wheat, but they were harassed by rodents such as rats. These rodents attracted wild cats. In order to be able to get shelter while preying on rodents, wild cats also entered the villages.

Until 5,500 years ago, Ma was initially domesticated by people in the Kazakhstan region and used to obtain dairy products and rides.

But unlike dogs and horses, cats have not been fully domesticated despite decades of living with humans.

By harnessing the social nature of dogs and horses, humans make them think of people as leaders within groups, obeying human commands, and thus domesticating them.

But the social structure of cats is completely different. Before you understand each individual, you cannot determine which social structure it is in. Their social structure depends on different lifestyles, and if there is no need to breed or raise a baby cat, the cat may live alone. But they may also form small groups and may even live in large groups.

The composition of the cat population is related to the amount of food, the sex ratio, and their individuality. In this highly uncertain social structure, hierarchy cannot be discussed. Therefore, it is also difficult for them to listen to orders from the same kind or human beings.

The cat just happened to be a pet

From the perspective of diet, cats did not have the opportunity to become domestic pets.

Like all felines, wild cats are natural carnivores with well-developed canines and short digestive tracts, which have limited metabolic capacity and can only digest protein, and wild cats rarely eat plants.

In addition, they need to constantly supplement taurine to maintain good health. The lack of taurine in the diet can cause problems in the cat’s retina and even blindness. If there is no taurine, the cat’s heart function will also be greatly affected. The main source of taurine is meat.

However, the long-term food of ancient humans was in a state of shortage, and the domesticated animals at that time often only considered practicality. Take the Middle East as an example. Animals that were domesticated during the agricultural revolution mainly included cattle, sheep, goats, chickens, etc., mainly for meat and milk.

The purely carnivorous cat master and the ancient humans who are also in desperate need of protein clearly have conflicts of interest. There is no reason to believe that humans will actively choose cats as family pets in the early stages of the agricultural society.

The most reliable reasoning is that people in the early days of the agricultural society tolerated cats approaching their lives, making wild cats a domestic cat, but not domesticating them. Therefore, the integration of animals such as dogs and horses into human society and adaptation to being led by humans is largely the result of artificial selection, but the appearance of the original domestic cat is entirely a product of natural selection.

At present, there are more than 400 breeds of dogs approved by the Dog Breeding Association, including both Teddy and other popular dogs. The shape, shape and ability between dogs and dogs have been produced. A big difference.

In contrast, cats are consciously and selectively bred for less than 200 years. More than 97% of the 1 billion domestic cats living today are randomly breeding. Some of the purebred cats we are talking about, Some have only started breeding in the last thirty or fifty years, and most cats have little difference in body shape and characteristics.

In addition to the low degree of domestication, the “cat master” can sell mixed food and drink, and Wu Neng can hunt and eat. Although they are hunting and stunting, they perform tasks with a temperament.

The zoologist at the University of Oxford did an experiment and found that the cat did not even have a high level of enthusiasm for the mouse in our imagination. Only by investing a large number of cats in a limited area would it be possible to eliminate the rodent, and From time to time, rewarded with milk, “cat master” has the power to catch rats.

Cats who can do their own work are so casual, and of course they can’t count on them to do their best for the police uncles.

The ability of the cat is not suitable for the police

In addition, the ability of the cat itself makes it incapable of the police.

As a helper of the police, the ability of dogs and horses to be matched is mainly search and ride. Cats on riding are definitely not good, but the ability to search for drugs, search for explosives, and search and rescue, the cat does not seem to be so powerful.

For animals, the search ability relies mainly on the sense of smell. Although the cat’s sense of smell is much higher than that of humans, it is still not comparable to dogs.

Domestic cats are 14 times more powerful than humans, but dogs are 1000 times stronger than humans. This is not the most sensitive type of smell in dogs. As a specialized kind of sniffing dog, the sense of smell is 1 million to 10 million times stronger than human beings. The blood hunter’s sense of smell can be even 10 to 100 million times higher than humans. In contrast, the cat is certainly not the best helper.

Of course, this is not absolutely true. Under the food, there must be a brave man, and the comet has a special case. In 2002, a checkpoint in Stavropol, Russia, adopted a cat named Rusik, which mainly searched for smuggled salmon and caviar.

Due to its excellent ability, it quickly replaced the work of other police dogs. However, after all, Rusik can’t be met, and the content of the search is very special. For cats who are determined to join the ranks of the police, there is no universal reference value.

Police cat’s “opening method”

There are also military agencies abroad that want to use the cat’s small size and hidden features to help them perform their tasks, but not as police and law enforcement, but as spies.

In the 1960s, the CIA launched a project called “Listening Kitty”, which plans to monitor the Kremlin and the Soviet embassy by training spy cats. Through surgery, veterinarians implanted microphones in the ear canals of these cats and implanted small wireless transmitters at the bottom of the skull. The CIA can quietly record some of the sounds around them through these cats.

The $16 million project was terminated in 1967 and the project was subsequently declared a failure. In 2001, the CIA concluded in the declassified memorandum that they were convinced that they could train cats to take short-range actions, but given various factors, “it is not practical for (intelligence) purposes.”

However, blocking the road as a policeman, cat lovers do not have to be too upset. Back to the beginning, the British police station said that after careful consideration, they decided to recruit the first police cat in the UK.

However, they did not think about what the police cat should be responsible for. If nothing is done, the police station may use the cat as a mascot.

Perhaps inspired by Eliza, the Troy City in Michigan, USA, also recruited a small police cat named Donut. Its only task is to bring happiness to other police officers.

It seems that the “correct opening method” of the police cat was finally found. In this world of “face value is justice”, Meng is enough. After all, if you are born as a cat, you can sell it for a living.
