"They live like a cat with a dog" - a famous expression.
So they say about people who constantly quarrel about and without.
The idea of the enmity of cats and dogs is so common that people often do not even think about why this happens.
By science ...
Historically, cats have never been the prey of dogs. Therefore, you can not draw parallels with the cat and mouse. Nevertheless, for some reason from time immemorial these animals can not make friends.
Scientists have several versions on this subject. Basically they are built on the difference in the "languages", characters, types of behavior of these animals. These differences are noticeable even in the obvious: the cat wags its tail when it gets angry, and the dog - when it rejoices.
Both cats and dogs are naturally hunters. But they hunt completely differently. Dogs are hardy and used to drive their prey, running huge distances. Cats do not know how to move so fast and are not strong at all, but they can quietly creep towards the victim. Therefore, cats do not have a specific smell, and dogs express a smell of dog.
Another version of scientists is geneticCompetition of species. It is possible that the ancestors of cats were saber-toothed tigers, which were able to offend the ancestors of domestic dogs. Scientists believe that the current dislike of dogs for cats is due to a genetic desire to take revenge on the descendants of their enemies.
Another argument - cats and dogs just do notHave got used to each other. Not all, but most people are clearly divided into "dogs" and "koshatnikov." Those few who decide to bring both a cat and a dog are often perplexed - why are they considered enemies? After all, a kitten and a puppy, from early childhood living near, almost always become best friends. But the fact is that these animals get used to each other. A dog that is not accustomed to a cat, there is an irresistible desire to chase this noisy fluffy lump, while the cat is frightened by the attack, begins to defend itself and run away.
In addition, your own territory is important to the cat. That is why cats often mark places that they consider to be their own. Any invasion of another animal, including a dog, in this place is perceived as a signal to action. The dog responds to any attack. Since the speed and strength of the dog often wins the cat, for the latter, in most cases it ends badly.
... and according to rumors
Of course, over the long years the feud of dogs and cats has overgrown with many legends and beliefs. Perhaps the most beautiful legend is about the poor man and the magic ring.
A very poor man did not succeed -There was no harvest, there was no fish caught in the river, everything fell from the hands. But one day he found in the forest an ordinary ring - and life after that was fine. The cat thought that this ring was magic, and it was thanks to him that things went uphill.
The cat let slip about this rich man, whoCame into the house and took the ring from the poor man. Wanting to help the owner, the cat and dog stole the ring from the rich man. But on the way home the dog fell asleep. The cat returned the ring to the owner, saying that she had extracted it herself, and the rich man had been told about the ring by a dog. Then the owner kicked the dog out into the yard and began to feed the scraps, and left the cat in the house and fed from a bowl. Such a betrayal the dog did not forgive the cat.
