Focusing on the core question of "why does the weasel let out stinky farts", this paper introduces the classification attributes, appearance characteristics, distribution range, habitat habits and feeding characteristics of the weasel (originally known as the yellow weasel), explains the location of its stinky farts, odor components and its role as a means of self-defense, mentions that most weasel animals have the ability to release stinky farts, and introduces the weasel's cousin, the white weasel.

Focusing on the theme of 'Why are dogs so close to people', this article introduces that dogs have a strong ability to understand human intentions, are the most loyal of all domesticated animals, can undertake multiple functions, and are irreplaceable right-hand assistants to humans; Dogs were domesticated by wolves and are the first wild animals domesticated by humans. There has been a long controversy over their origin and location in the academic community. In recent years, molecular biology research has shown that dogs are most likely domesticated by gray wolves, but the origin place still dates back to about 16,000 years ago. Originated in China, and originated in the Middle East 13,000 to 12,000 years ago. Dogs have been associated with humans for more than 10,000 years. Although they occasionally spread zoonosis between humans and dogs, they are still mankind's closest animal friends.

This article centers on the question of "why cats have trouble with rats". First, it explains that although rats can steal food, chew furniture and spread plague, they are important food sources for many carnivores from the perspective of food chain. Then it explains that cats like to prey on rats because rats are comprehensive in nutrition, rich in taurine that cats cannot synthesize themselves, and can maintain night vision. Moreover, rats are abundant in number. At the same time, pet cats that do not eat mice need to be properly supplemented with taurine-rich foods, and the large number of natural enemies of mice is still a miracle in nature.

This article answers the question "Why do cats have nine lives?", explaining that this statement does not mean that cats can die nine times, but that cats have strong survival ability. It also explains the reasons why cats are not easy to die from aspects such as outstanding running ability, ability to swim, and ability to soft landing at high altitude., strong healing ability after injury, outstanding combat effectiveness and hunting ability

This article answers the question of why Yellowstone Park in the United States introduced wild wolves. It introduces the long-term killing of wolves by humans, which led to the proliferation of deer herds and ecological imbalance in Yellowstone Park. The ecology gradually recovered after the introduction of wild wolves. It explains that wolves, as the top consumers in the food chain, play an important role in maintaining the balance of the ecosystem, and also mentions the change of people's concept of wolves and the development of wolf protection work in various places.

This article introduces the reasons why nocturnal wolves like to howl at night and the various functions of howling. It also mentions that zoologists will find and study wolf packs by imitating howling.

This article answers the question of why the golden leopard drags its prey onto the tree, and introduces the appearance characteristics, number of subspecies and distribution range of the golden leopard. It shows that due to the existence of strong enemies such as tigers, jackals, and wolves in the habitat environment, the golden leopard is good at climbing trees. Climbing trees will keep food and avoid danger by dragging its prey onto the tree.

This article focuses on why cheetahs cannot chase prey at high speed for a long time. It introduces cheetahs 'extreme running ability and adapted body structure. It explains the reasons from the two aspects that the respiratory and circulatory system cannot keep up with the needs of anaerobic exercise, and high-speed running produces too much heat and is prone to collapse. It also mentions cheetahs' hunting strategies and the survival situation of prey that is easy to be robbed.

This article focuses on the reasons for the birth of white tigers, explaining that white tigers are not freaks, but albinism caused by some genetic mutations. The probability of occurring in natural conditions is about one in ten thousand. In ancient times, wild white tigers have been recorded. Nowadays, most common white tigers are artificially bred. There are also albino animals such as white snakes and white frogs in nature.

The theme of this article is "Why tigers are poisonous and don't eat their young", explaining that even if a mother tiger is hungry, she will not eat her cubs, and will do her best to protect her cubs and teach her hunting skills. At the same time, it is pointed out that this maternal nature is not unique to tigers, and many animals will cherish their cubs and often rely on their smell to identify their own larvae.

With the theme of "Two tigers cannot be accommodated in one mountain", this paper introduces the tiger's habit of living alone and the way to mark the territory, explains the cause of this statement from the ecological laws of energy transmission in the food chain, and points out that over-development of mountains and forests leads to the tiger's lack of food and survival. The current situation facing severe threats.

This paper focuses on issues related to lions and tigers and introduces the origin of lions and tigers: wild lions and tigers have basically no intersection living environment, it is difficult to mate in the wild, and there is a low probability of producing hybrid descendants under artificial breeding. The article clarifies that the two do not meet the definition of species and are not new species. It also mentions that human artificial interspecific hybridization has a long history.
