What makes a predator to approach human habitation

Woe to rats, mice and voles, if a ferret will find a loophole in those areas where they settled for the winter. Neither cat is level with him in the art of exterminating rodents. And if only it was occupied by a ferret, a person could only thank him for his visits. But a ferret is not harmless: penetrating into the coop, he will spare no there is no bird. Lusk late autumn, not only settles closer to home, in the yard among the wood, under stacks of straw, but the climbs and in hiding in barns and sheds, and until the spring produces there own food. This sleek little predator (no longer than 20 cm) is perfectly adapted for hunting small rodents, narrow body allows it to penetrate into the closest hole. From petting mice have even worse than a ferret. Weasel and gets to the sparrows, pigeons and up in the dovecote, and sometimes goes to poultry. Yet the benefits of her man more than harm. Extermination weasels would lead to the reproduction of mice and voles. Similar role with ermine weasel performs very similar to it, but a larger animal. So filled with autumn temporary housing rights young visitors and guests. Not knowing that the man gives shelter to a whole tens and hundreds of unwanted tenants present themselves to seek protection, heat or food under its roof. Some of them are rather useful. Much of the harm. We should be well studied and these and other: you know well and my friends and their enemies.
