Cats are lively pets, yet they are fierce fighters and remarkable hunters. They are fascinating animals that capture human attention and charm our hearts. Cats are among the most beloved pets, but we still don't know much about them. Therefore, some of the world's leading cat experts are conducting scientific experiments that challenge common knowledge to study the secret lives of our feline friends. What happens just before a cat attacks its prey? In the blink of an eye, they can catch it. How could they become such formidable creatures in the animal kingdom? Their research will overturn our perceptions of cats. Now, let’s observe how these adorable pets transform into fierce predators.

The research team has been tracking cats for about a month, taking photographs and conducting experiments. The collected information is relayed to the Cat Research Department, where Professor Allen Wilson from the University is using GPS technology to determine whether the cats are hunting or simply wandering around. There might be something significant hidden in their behavior. The research team aims to uncover the wild instincts concealed in the appearance of domestic pets. First, they need to observe how these cats hunt. The subjects of observation are wild cats on a farm in Davis, where the presence of mice has become a problem. They wondered if having cats would reduce the mouse population. Traditional methods were ineffective and costly. So, they asked a friend who raises semi-wild cats to bring three slightly younger cats, and they are very satisfied as the mouse problem has completely disappeared. Capturing footage of the cats hunting is quite a challenging task; they need to understand how the cats behave while hunting.

Therefore, the research team attached GPS trackers to the cats. When looking at the data, Tom was seen hunting along the road, heading towards an area about 1 kilometer away. Over a 24-hour period, the cats dispersed throughout the area, which spans the size of 15 soccer fields. However, the cats primarily spent their time hunting within the farm. Cat behavior experts Dr. John Bradshaw and researcher Robin Smith aimed to observe the cats using special cameras. Now, all that was left to do was wait. The cameras captured footage of foxes, chickens, and several cats. Finally, they were able to obtain very rare footage. Let's take a look at the video of a cat and a mouse. It was a quick moment, but it was impressive. This is a predator that you wouldn't see in a pet cat. These creatures hunt to survive and thrive.

They sneak around, watching the farmer until a mouse catches their eye. We can't see anything, right? Then they pounce and quickly run to attack their prey. The hunt is over in less than two seconds. What is the secret to such quick and precise attacks in such a short moment? Please catch a cat. Hello, a team from Royal Mathematics University is preparing an experiment to find out how cats can hunt so instantaneously. They are analyzing the precise movements of cats. They are attaching something to each of the main joints of a cat named Lio. They intend to capture it with a high-speed camera. They are measuring how it moves. Alright, let's do it again. They are trying to analyze how it places its feet. One fact that can be determined from the experiment is that cats do not fully extend their legs.

고양이가 훌륭한 포식자가 될 수 있는 이유라고 합니다. 고양이의 골격 구조를 보면, 웅크린 자세에 적합하게 되어 있다는 것을 알 수 있습니다. 팔꿈치가 휘어져 있고, 그래서 고양이는 아주 민첩하고 자기 몸을 잘 통제하며, 심지어 숨어 다니는 데도 능숙합니다. 허순 교수는 집고양이뿐만 아니라 고양이과 동물 모두를 관찰하고 있으며, 얼룩 고양이와 호랑이의 공통점을 찾는 작업을 하고 있습니다. 실험실에서는 애완 고양이와 호랑이가 웅크린 자세에서 구분하기 어려울 만큼 비슷하다는 것을 발견했습니다. 바로 이 웅크린 자세가 고양이의 특성 중 하나입니다.

It is the source of power that attacks prey in an instant. We filmed a tiger in the water using a high-speed camera. It was lying still and then sprang out at an incredible speed; the tense leg muscles act like springs. The footage is played back at ten times slower than real time, so it is truly lightning-fast in reality. Even more amazing is the unique ability of domestic cats. They may be smaller than other felines, but considering their size, they possess the same strength. Furthermore, their remarkable flexibility allows them to be superior in some aspects. Cats, among felines, have an astonishingly flexible spine. They can easily perform twisting movements, which large predators cannot do due to their stiff spines. Generally, in the feline family, the larger the body size, the less capable they are of performing difficult movements. Small domestic cats can do incredible things.

While they show their abilities, if these creatures were as large as lions or tigers, they wouldn't be able to do so. X-ray results show that cats have a posture similar to that of tigers and lions, and they are even more agile than them. However, what is more important than posture is the instinct of cats. If we can understand their instincts, we might be able to answer many questions that cat owners have. Most pet cats eat the food provided at home, so they do not need to rely on hunting. But why do they continue to hunt? Among cats living with people, those in small towns tend to hunt more frequently. After checking with GPS, it turns out that cats leave their homes, quickly survey the neighborhood, and then head to the forest to hunt. A cat can walk up to 2 kilometers a day and is successful in hunting about three times a week. The cat named Sandwich is just over a year old, pretty, and friendly, and is three years old.

I get along well with my pet. However, at night, it transforms into a hunter and brings back prey from somewhere. So far, it has only caught and eaten mice and rabbits, but since there are farms nearby, who knows? There are times when I'm surprised to see it bringing back something three times its size. 

Sandwich hunts in a unique way. It is currently in the woods at 2 PM. Listen to this; it seems to be mimicking bird sounds. No one knows why it makes these sounds. Is it trying to lure in its prey? At one time, I had a lot of trouble with mice, and having it catch them was a great help. But now, that is no longer necessary. 

Sandwich has been catching mice every day. It didn't want to eat cat food at all; it preferred fresh meat instead. It has stopped hunting.

많은 노력을 기울여서 가장 비싸고 좋은 사료를 먹여 보기도 했습니다. 하지만 사냥을 멈추지 않더라고요. 고양이를 키우는 사람들 중 상당수는 먹이를 많이 줌으로써 사냥을 멈추게 하려고 했지만, 그게 고양이의 사냥 본능을 충족시켜 주지는 못합니다. 연구 본부의 행동 전문가인 사라 엘리스 박사는 샌드위치가 집안에서 쥐를 쫓는 영상을 보여줍니다. 혼자 떠돌아다니는 고양이들과 조금 다르게, 집고양이는 쥐를 쫓을 때 순서에 따라서 행동하는 경향이 있죠. 우선 먹잇감의 위치를 정확히 파악하고, 달려가서 잡은 후에 물어 죽입니다. 그리고 먹이를 잘 다뤄서 먹기 좋은 상태로 만듭니다. 새라면 털을 뽑고, 다른 동물이라면 잘 흔들어서 뼈와 근육이 쉽게 분리되도록 한 뒤에 먹는 겁니다. 그런데 지금 샌드위치는

They keep shaking the prey that is not even dead yet. This is a change in order. The reason for this behavior is probably that the owner feeds them every day. They have a hunting instinct, but since they are not hungry right now, they do not feel the need to kill their prey. 

The speed at which cats catch their prey is closely related to their appetite. However, just because they are full does not mean the desire to hunt disappears. Cats' ancestors had to hunt to survive. But even if they were hungry, they still had to hunt. Dr. Brad Sure asked the farm owner to give the cats a special type of food: a dead rabbit that doesn't require them to hunt. A black and brown cat approaches first, among the two-week-old kittens.

Rabbits eat diligently. To provide for their young, they need to consume a lot. This little one can even easily chase away cats that are much larger than itself. The obsession with fresh meat is one of the most important survival instincts for felines. Many animals eat meat, but for cats, it is a means of survival. Felines have short intestines, which makes it difficult for them to digest plant-based proteins, and amino acids that are not essential for us are very important for them. Consuming taurine is also essential for their health. Humans can produce the necessary taurine in their bodies, but cats cannot. Therefore, they must obtain amino acids and taurine from animal proteins found in meat. Besides taurine, they can only obtain 18 essential nutrients through a carnivorous diet.

There are people and dogs, but it's enough for cattle. Cats can obtain all their nutrients from dead animals. By chewing on bones, they can take in calcium. Cats are also known for not drinking much water, as they can obtain moisture from meat. In fact, cats get most of their necessary moisture from meat. Their wild ancestors lived solely on meat. They have evolved accordingly, so they can get all the moisture they need from meat. From large cats to small ones, they all inherit their ancestors' hunting instincts. However, cats will soon face significant changes. It has only been about 30 to 40 years since we learned what nutrients cats need. Before that, cats had to hunt outside to maintain a balanced diet and reproduce. So, in 50 or 100 years, we will see...

어떻게 될지 모르죠. 사람이 고양이에게 필요한 분을 다 줄 수 있다면, 사냥을 훨씬 덜 하게 될 수 있죠. 고양이의 본능은 사라지고, 길들여져 가고 있는 건지도 모르겠습니다. 한 달로 계획된 연구 기간 중 반이 지나는 동안, 고양이들은 어떻게 지내고 있을까요? 추적 결과를 보면, 디나스키 같은 도시 고양이들은 집에서 50m 이상 벗어나는 일이 드뭅니다. 마을 고양이들은 조금 더 멀리까지 갑니다. 샌드위치는 집에서 300m 이상 떨어진 곳까지 가고 나죠. 가장 멀리까지 돌아다니는 것은 그로울러 같은 시골 고양이들입니다. 활동 반경은 농장으로부터 1km 넘습니다. 지역에 따라 활동 범위는 크게 다르지만, 이들에겐 흥미로운 공통점이 있습니다. 모두가 익숙한 길을 선호하고, 반복해서 똑같은 길로만 다닌다는 겁니다. 놀라운 건 고양이들 각각이

Every day, they move in the same direction. Each has a predetermined path. When hunting, they stick to the same route every day. They travel only along these familiar paths, avoiding each other's territories and dividing the area into three main parts. Meanwhile, in cramped urban settings, they employ even more sophisticated methods. Look here, cats divide their territories not only by geographical space but also seem to manage their time well. It's like saying, This land is mine in the morning, and yours in the afternoon. Even in densely populated areas, they distribute their time this way, ensuring their territories do not overlap. Territory is extremely important for cats. By dividing space, they minimize encounters, and without encounters, there are no fights. Generally, cats do not want to fight because it would be detrimental to them; they could get injured or even killed. So,

We divided the area and set boundaries so that they do not meet. We examined how similar the body structures of cats and tigers are. According to big cat expert Tiger Sturbin, these two show remarkable similarities when it comes to defending their territory. Tigers, unlike humans, do not form close-knit social groups; they are solitary animals that only overlap in territory with others. Tigers mark their territory with scent, ensuring that other tigers can smell it and avoid encounters. Tigers have scent glands similar to those of cats located on their face, head, and paws. This is important for tigers to communicate and form a type of bond so they can recognize each other. Wild tigers can clearly identify their family members, especially females, by their scent. Tigers mark their territory with scent.

To avoid encounters or fights, they display signals. However, not all felines keep their distance from each other. A clear difference is shown by lions. Lions have evolved to hunt in groups as needed. They often need to catch very large prey, so they gather together to combine their strength and hunt more effectively. The territorial instincts of big cats have evolved according to their environments. Just as a tiger living alone in the jungle is different from a lion that hunts together on the savannah. So, which side are domestic cats closer to? Experts at the Cat Research Center have been reviewing footage for hours. They captured city cats urinating in gardens. If their territories overlap and problems arise, what will the cats do?

Please expand on this. Professor Alan Wilson discovered that the territories of two urban cats overlap in the middle of the street. One of them is hiding, and the other seems to be able to go up or down, but it doesn’t. Clearly, there has been some interaction between the two cats, which is why one cannot use the entire area. Perhaps in the past, Smudge and Oji have confronted each other in the middle of the street, and since then, they choose not to risk going that way. The research team attaches cameras to the cats to learn more about the situation. Oji seems to notice something while walking down the street and hurriedly turns back. Oji lives on the opposite side of Hannover and usually stays close to the roadside. I think I've seen him before, coming to play in the garden and sitting on the fence, also resting in the sunlight. I’m sure I’ll recognize him.

She's a pretty cat, but I can see her pride and she gives off a bit of a tough vibe. My cat often gets into fights, but she hasn't had any with Oji. She likes to sit on the car parked across from our house. The owner is often surprised by her rough demeanor. I dreamt of a peaceful life, wishing I had a little cat that liked to play on my lap. Oji is her name. From the moment she arrived here, I knew she was no ordinary cat. She would attack people on the dark stairs and chase them while growling. Ever since I put a name tag on Oji's collar, I've been getting calls about her. One day, I received a call from a fishing supply store saying Oji was there. They suggested I take her in for her anxious behavior. I thought, So that's where Oji was. Another time, I heard from a neighbor who lives across the street.

A student called to say that Oji has been with him all day eating potato chips. There was a time when a neighbor living across the street was surprised to see Oji and remarked, Oh, I guess this cat comes here too. So, I told them that Oji is our cat. Oji isn't wandering around for no reason; he claims this street as his own. He thinks this is his territory and is diligently protecting it. When a strange cat appears or when a young cat that has been living in the neighborhood grows up, Oji feels the need to defend his land and makes sure to mark his territory. I won't mention where he has marked his territory because I think the neighbors might not like it. He also gets into fights with other cats to settle things. I wonder why he does that. Honestly, I have no idea. He has always been like this; it's clearly just his nature. It's not my fault.

Originally, that's how it is, and that's for sure. At 10:20 PM, Oji is wandering the streets. It's a neighborhood where you could recognize everything even with your eyes closed. Cars skillfully avoid him. The next day, around sunset, Oji is patrolling his territory when suddenly Smudge appears on the wall. They stop and lock eyes with each other. Oji retreats first. It was a tense situation. Experts believe there is animosity between the two. Richard Harvey, a specialist, invites Oji, the criminal, to a permanent stay. Is Smudge a one-eyed creature? Yes, that's right. I think I've seen him before. It seems that Smudge and Oji do not want to meet each other. They've divided the streets. It seems that was decided a few months ago regarding who would take which area. That’s probably the reason for the conflict. Yes, that's right. It’s noisy. That side has its half, and Oji has his half, so it’s settled. Half is half.

It's a wild area. It's nice to see that there are only these two cats roaming around the main road. The other cats hardly go beyond the backyard; even when they do, they just move around the vicinity of my house. But the wild cats venture quite far from their city home. They roam the streets continuously, almost like they are the leaders of this neighborhood. It seems like their territory is broader than Smudge's. So, that means they are winning, right? Oji is the leader. I figured as much. The city cats live by dividing the streets into territories, just like tigers do. However, during my observations, an incident occurs that disrupts this balance. Another cat appears. At first, it only showed up during the day, but one night, Smudge was caught on camera hiding under a car. After a brief standoff with some growling, Smudge retreated to a safer home.

The returning spiral cat invades not only the smudge area but also the wilderness area. The wilderness is being pushed back. These days, I feel quite anxious. The opponent is a young gray cat that seems to have a lot of fighting experience. Its ears are torn in several places, and even when the wilderness makes noise, it doesn’t run away. One night, a fight broke out between the wilderness and a new challenger, and the owner of the wilderness had to step in to stop it. The opponent approached first and cornered the wilderness. So, the wilderness tried to get help, but that’s when it started attacking. However, the opponent was too strong. In the end, the wilderness had to receive a tetanus shot and antibiotics. It’s a minor injury, so a human would recover quickly, but cats are different. The throne of the wilderness has shifted. I will observe this cat to uncover the reasons for its obsession with fighting, and once the research is complete, I will disclose the results.

It has become clear that city cats fight each other to defend their territory. But what about rural cats? Tom wandered around at midnight and encountered a small kitten. They affectionately touched noses before going their separate ways. There were no mind games or fights. The cats living on the farm get along without quarrels, and this is all related to the distribution of food. Problems arise when there is not enough food compared to the number of cats, leading to competition among them. The farm has an abundance of prey, like mice, providing plenty of food for the cats. However, the prey of felids is generally spread over a wide area. This affects the relationships between cats. While cats can hunt alone, on the farm, they come together to protect their shared territory from intruders. Cats on the farm have many...

While spending time together, they protect their territory because the farm is their place of refuge. Here, they can raise their young, so it's very important for the female cats to protect their area from outside cats. The cats living on the farm gather together like lions in a pride. In contrast, the city cats living on the busy streets of Brighton maintain their own territories, living like solitary tigers. So, what about the cats living in small towns? They have wide fields and cozy homes. What kind of life do town cats prefer? GPS tracking results show that some cats live close to city cats' homes, while others roam far away like country cats. There’s a cat going towards the town along the roadside fence. It's quite a long way, even for a sandwich.

It goes on. These two are not everything. The village cat is hunting at midnight. Safi roams outside the house for several hours. It even picks up strange passengers with eight legs. The reason why cats like Safi and Sandwich live a lifestyle closer to the wild compared to other cats in the same village is said to be related to how they catch their prey. Dr. Sarah Ellis from the Cat Research Department is examining the surprising traits of Safi. When the cat is about to pounce, this is not related to light; the surrounding brightness does not change at all. When a cat prepares to attack, its level of arousal increases, especially just a few seconds before it strikes its prey. Just before attacking, Safi starts to sway its body back and forth while keeping its center behind.

Since there may be a lack of blood, this is how we warm up the body. It is a preparatory movement to run forward and attack the target. The appearance during the attack is even more interesting. When shown a small bird or a mouse model, all the cats attack without hesitation. However, when they encounter a larger mouse, the situation changes. Most cats tend to retreat, while only a few, like Sappy, will attack. I was surprised to see them display the same reactions as when they actually see prey. They growl or make hissing sounds. I thought they would just leave the mouse model alone since it was quite large, but as soon as they saw it, they attacked. They would grab it with their mouths, paw at it, or wrap their whole bodies around it, making it hard to take away. Catching a mouse requires considerable skill.

Among the cats being observed, not many show such skills. The researchers, who were impressed by this sight, invited Han Nal, Safi's owner, to the research headquarters to hear more about it. The last thing is something I'm not sure about, but it looks like a small mouse. How did Safi catch it? There might be a reason why she is good at hunting. I brought Safi from a farm, and her mother probably was a good hunter. If a cat is good at hunting, we can usually find a reason in its upbringing. There was a good example. Cats that did not learn how to hunt from their mothers tend to be very poor hunters. Every cat is born with a strong instinct to hunt prey. We can see this even in the young cats in the laboratory. However, instinct alone is not enough before they turn one year old.

사냥에 필요한 기술을 어미로부터 배워야 합니다. 연구팀은 농장에서 새끼 고양이가 사냥을 배우는 모습을 카메라에 담았습니다. 이들은 검은색과 갈색이 섞인 어미의 새끼입니다. 어미는 생후 주된 새끼들에게 스스로를 지키는 방법을 가르치는 중입니다. 어미가 갈색 새끼를 데리고 사냥을 나갑니다. 새끼는 흥미가 없어 보이지만, 어미는 계속 새끼를 부르며 설득합니다. 새끼는 또래 고양이들과 놀고 싶은 모양입니다. 어미는 할 수 없이 혼자 갑니다. 30분 후, 어미가 먹이를 물고 돌아옵니다. 어미는 잡은 쥐를 혼자 먹지 않고 새끼들을 부릅니다. 마침내 새끼 한 마리가 달려옵니다. 이렇게 어린 고양이는 나중에 살아 있는 것까지 다 잡을 수 있게 됩니다.

We learn the correct techniques for catching. Since he has been practicing from a young age, he investigated the cat and found that he and the sandwich tied for first place. Cats, like other felines, instinctively hunt and continuously patrol their territory. However, unlike other animals, cats do not remain in the wild but have chosen to live alongside humans. How could cats adapt to a life as pets with people? Unlike wild cats, domestic cats are not afraid of humans. In fact, some of them eagerly follow their owners, just like Dwa Do. There is a position called the baby pose, and when I show this position, Ted comes under my legs and sits down. He may not understand yoga poses, but he has his own comfortable position.

Ted and Dora are receiving special attention from experts. They look like typical house cats, but they were actually born on a farm located about 600 meters away, which is their rural hometown. On that farm, 36 kittens were born. At that time, we already had two cats, so we told the farm owner that we didn't need any more. That's how Ted came into our home. His fur is so soft, and his gaze is incredibly affectionate, so I told my husband, This cat is adorable, what do you think? He said it seemed fine. He loves being with us. In the evenings, when we sit at home, he always comes over to us. Oh, our Ted! Although Ted was born on a farm, he seems to have completely forgotten his past, as we can tell from the GPS tracking results. Let me show you the data. Ted is different from other rural...

Cats don't go very far. The distance to the farm is only 600 meters, but they don't return to the farm. They spend their time in the yard like city cats. They have become completely different cats. Did I say different? Their lifestyle and behavior are entirely different. Country cats go quite far to hunt, but Ted here behaves just like an ordinary pet cat. Why has Ted, who lived a life close to the wild on the farm, changed so much? Dr. Rachel K.C. says that if cats are well trained, their wild instincts can be activated. Rachel is responsible for helping the cats at the rescue center adapt to city life. These cuties are two weeks old. The period from two weeks to eight weeks is very important for the development of a cat's brain. This period is called the socialization period, and it is filled with fun and surprises.

This is a time when kittens begin to integrate information received through their various sensory organs, such as sight, smell, hearing, and touch, and start to learn many things. It's crucial that we make good use of this period biologically. This way, when the cats grow up, they can adapt very well to urban life. One of the most important aspects is getting them accustomed to people. For example, even when people look at a cat's ears or mouth, the cat should not feel uncomfortable. Therefore, we aim to help the cat gradually get used to such situations. This includes scenarios where a person touches or holds the cat. We need to ensure that the cat does not feel uneasy about any of this and instead accepts it positively. This way, they will come to regard being with people as just a normal part of their daily life. The wildness of young cats...

To prevent anxiety, it is important to expose cats to various experiences before leaving the structure center. They should meet both male and female children, be introduced to different cats or dogs, and be allowed to smell various scents. They should also be exposed to sounds like a baby crying or a vacuum cleaner. This way, cats can adapt to strange and unfamiliar things, making the most of their socialization period when their brains are still developing. Without sufficient adaptation time, cats are likely to feel very anxious in unfamiliar environments. This can lead to various problems, such as hiding upstairs when a person enters the house or avoiding children or dogs. These issues can arise when they encounter situations they have not experienced during their early development. Ted and Dora, who were born on a farm but happily interact with people, differ from other cats living 600 meters away due to their early socialization experiences.

It was a two-month experience. I realized that in order to give away cats as pets, they need to be accustomed to people beforehand. When they reach four weeks old, I start to take care of the kittens. I feed them, and before long, they learn that I am the one who brings food and come to me first. It's quite a commotion. If I train them this way, when someone comes to adopt a cat, they will be able to adapt quietly and well. Cats born in the rough environment of a farm, like this one, can transition into life as a pet. 

In fact, cats are animals that cannot be completely domesticated. They possess the ability to freely switch between their wild instincts, as hunting animals, and the subdued behavior of domesticated pets, a skill inherited from their ancestors.

You could say that they are long-lived. However, domestic cats typically live about half as long. The reason cats are special is that they have the ability to adapt well, whether in a home environment or in the wild. Most other felids do not possess this ability. Whether large or small, felids are typically cautious around predators. In this case, the cautiousness may allow them to approach a predator without fear, but it cannot be said that a bond has formed between them. A bond is something that develops over a long time when an animal learns to communicate more deeply with humans. There are many similarities between cats and other felids. They all defend their territory and are carnivorous. Their body structure and movement patterns are also similar. Every day, we see the wild nature in cats. However, they have learned how to live alongside humans. It is precisely this ability that makes cats beloved by people.
