Chương 753: Chapter 753: Stray cat
Fang Yedao: "Under normal circumstances, a healthy ecosystem will form a net-like relationship, in which the number of various species increases and decreases, but they are all maintained within a certain range, allowing the ecosystem to maintain a dynamic balance.
But when cats that weren't among them joined, they preyed on birds, weakening the ecological system's ability to restrict insects, making raptors and medium-sized beasts that also feed on small animals lack food.
The ecosystem is formed through long-term evolution. After hundreds of thousands of years of competition, exclusion, adaptation, and mutual assistance, the species in the system have formed the current close relationship of mutual dependence and mutual restraint.
After an alien species is introduced, it may be excluded from the system due to its inability to adapt to the new environment; if there are no creatures that can compete or restrict it in the new environment, it will become a real invader, breaking the balance, changing or destroying the local area. The ecological environment seriously damages biodiversity.
Regarding the ecological disasters caused by cats, the most famous one is a cat named Tibbers, which killed all the unique bird species on Stephen Island in one year.
But that is a closed island environment. No animal can deal with the perfect predator of cats. In China, in the wild, predators of the same niche such as leopard cats and red foxes restrain them, and stray cats cannot make waves.
But in cities, stray cats that should have been eliminated by nature can eat food waste, or even be fed by humans, allowing them to multiply and reach a population density that is impossible for small carnivores in nature.
The number is abnormally large, and they are animals that are fed and bored to hunt because they play, so stray cats are a big problem in cities.
It is not only the impact on birds and other animals, but also infectious diseases such as toxoplasmosis and rabies, which bring hidden dangers to public health and safety. "
Some netizens who like cats and even fed them, listened to Fang Ye's explanation, and couldn't help feeling a little ashamed.
When I fed them before, I didn't understand this, I just thought I was caring and kind.
It turns out that random feeding is not a good thing, and it is the same type of operation as random release.
Netizens couldn't help asking: "What should I do then?"
Fang Ye said: "The root cause is first, don't let the cat become a stray cat.
Keeping pets is a matter of money and energy, but many people only think of the fun brought by pets before raising pets. They didn't expect the troubles caused by pets. If they don't want to raise them, just abandon them at will. This is very irresponsible. .
For example, in college, if you want to keep pets in school, they will not be allowed to raise them. They will keep them freely, and they will not take them away after graduation. In this way, there are more and more stray cats on campus.
Someone raises cats freely, or the cat slips out from the window, and can't find it after throwing it away. If you raise a cat, don't raise it freely. Remember to close the window to avoid this kind of thing. The cats that have been kept at home are also very healthy and long-lived. This is a fact. There is no need to think about letting them go outside. Going out may harm a few birds.
For stray cats, control yourself and don't feed them.
The standard of living of stray cats is definitely not as good as that of domestic cats. They will be hit by cars, thrown rocks, endure starvation and eat trash, and fight with other stray cats. Your feeding only improved its living condition for a short time, and when it reproduced, there will be a group of poor little stray cats in the city that are going to freeze and turn over the garbage.
While talking about how pitiful stray cats are and how hateful people abandon them, while feeding them, this is not a person who I hate.
The other is sterilization!
Some people are disgusted with neutering cats. They feel that the experience of neutering a part of their life after neutering deprives them of the right to give birth and makes cats unhappy.
In fact, this kind of thinking is entirely from the perspective of humans.
Animal mating is only based on instinct. Most of them don't feel happy during mating, or even an extremely painful experience. Cats have barbs.
After neutering, cats will not suffer from heat and mating, and their bodies will be healthier. What's wrong with them?
If you just feel that a child is not a cat, you know the joy of cats. If you are not a cat, how do you know that the cat is unhappy when mating, or you want to let the cat mate at least once, and give birth to offspring. From the point of view, cats do not have the concept of'I want to have a baby', their reproduction is only driven by genetic instinct.
You can calculate how many offspring can be born by allowing cats to reproduce without restriction.
A female cat can give birth to a maximum of 12, and a minimum of 2, usually 3-6. A cat with good physical strength can give birth to 2 times a year.
A pair of non-sterilized cats can breed 2 million cats in 8 years under ideal conditions.
You want to retain its right to reproduce, what about the right to reproduce its children? What about the child's child? Are these offspring capable of feeding and caring? What can't be taken care of, is it abandoned or given to others? Not everyone has the ability to raise a cat, just stuff it with others, and others raise it for a while and abandon it. Doesn't this become a source of stray cats? "
Fang Ye paused, and continued: "Capture, sterilization, and release, or TNR for short, is a more humane way to reduce the number of stray cats.
After the volunteers capture the cat in a safe way, let a qualified veterinarian perform a sterilization operation and immunize it. After the operation, the cat will be released to the original living area, and its ears will be cut off for identification to prevent being seconded. Operations. Some cats with friendly relatives can help them find an adoptive family.
If you want to keep a cat, I recommend adopting it instead of buying it.
TNR is highly praised by many people, but it is not a panacea needs to block the source of stray cats, reach 71% to 94% sterilization rate, and conduct centralized feeding management, so that it will be effective. It is very strict. The most important thing is not to feed at will, and don't abandon it.
In fact, there is no problem with three or five neutered stray cats in a community. It's okay to slap the stray cats. The happiness of the residents in the community can be improved, and the children can cultivate love, which can be regarded as being close to nature.
In protection work, it often starts with such a simple kindness.
But the hundreds of thousands of stray cats in a city far exceed the carrying capacity of the ecosystem.
As for hunting, the problem of stray cats is not a purely ecological problem, but also a social problem.
Simple and rude hunting can effectively reduce the number of stray cats, but it will arouse the resentment of many people, and the gains outweigh the losses.
It will only be used when the ecological environment is severely threatened, when protecting endangered wild animals, or controlling severe infectious diseases.
In fact, euthanasia is also a very good method, but it is also a question of acceptance. This requires us to continue to go to popular science. "
