Yes, there are already examples of both scenarios.I think everyone has heard of the street cats or wild house cats, precisely because they are such an ecological problem. Because it is such a large population, larger than it occurs in nature, and because they are successful hunters, cats have already eradicated many vulnerable species. So they stand their male though.
Also dogs can save themselves well without people.Because I know more about dogs, and think that most people know less about this than the wild cats, I will go into a little more.
Dog breeds, as they are now, cannot be maintained without human insertion.Pug dogs, for example, will be extinct in one generation. What you do see in populations of wild street dogs is that within a few generations the dogs return to a ‘ primetype. ‘ Depending on the regional climate, these types will look slightly different, but in warmer climates they will resemble, for example, Australian dingoes, and in colder climates they will have a thicker coat like the herder types. There is already a name for this type of dog in societies where large populations of wild dogs live without human input; The Paria Dog. [1 Here is an example of such a dog[2:
If you think that looks like such an expensive Shiba inu or a husky or Carolina dog, yeah that’s right.
One calls these primebreed breeds and breeders have a hand of saying that these are the oldest dog breeds. That’s not true, none of the current dog breeds is more than a few hundred years old. But if dogs were to live without people, they would probably look like this after four or five generations. An example of an Indian Paria dog:
You’ll also see that wild dogs are soon going to go among wildlife like wolves and coyotes.
There are therefore already these[3and coywolves: Dog-Coyote and coyote-wolf-dog hybrids.There is also a debate going on whether these new crossings should not be a new species, as they appear more intelligent and resilient than their respective ancestor species. It may well be the birth of a new species. [4 Coydog:
The most heartbreaking example of dogs that have adapted without people are the wild dogs of Chernobyl.
When the inhabitants had to evacuate in the aftermath of the nuclear disaster, they were not allowed to take their pets in the buses, because there was not enough space. People who have experienced it tell how the dogs kept running behind the buses with their owners long, and that some of the people begged to stop the bus so they could take them with them. The dogs were shot in many cases[5:
“Dogs howling, trying to get on the buses.
Mongrels, Alsatians. The soldiers were pushing them out again, kicking them. They ran after the buses for ages. ” Heartbroken families pinned notes to their doors: “Don’t kill our Zhulka. She’s a good dog. ” There was no mercy. Squads were sent in to shoot the animals. But some about and it is mainly their descendants that populate the zone. “
The descendants of these dogs who had to be left alive now still live in the alienation zone where people should not come for a long time.The lifespan of these dogs is not long, because of the radioactive irradiation to which they are exposed, but they do maintain themselves without humans. Now that there are more and more people in the area, there are organizations that try to bring these dogs to people, you can also adopt one. They are also included. But before man came back, they saved themselves, and they did well. The first people who returned to the zone found a population of about 300 dogs. Not much, but enough to educate themselves of what is in the area to be found.
I find it an interesting topic, as you see.
But cats and dogs will surely stand out without people.
Yes, that can be very easy.
That is already happening. For dogs, the great example is the Dingo.They have been created from dogs that we as humans have brought to Australia and are wild. Also in street dogs you immediately see the primest instincts coming back. On the street they know that where people can find their food is so easy to stay in the neighbourhood, but if you get them out of that situation and they have to take care of themselves they are going to hunt for small game.
For cats It is even easier: they are never full domesticated.All over the world, “Feril cats” can be found (not to be confused with a normal stray cat). As soon as a kitten is born and has no contact with people (stray cats usually teach their kittens that people are good) they develop into completely wild cats that are not even more tame as an adult. These cats take care of themselves and are just as wild as the foxes and badgers in our country.
Dogs and cats have been transformed into cuddly pets but once it has to go their instinct works and can most trouble-free without human life.
Katte帽 sure; Dogs probably not.
