A cat is not only a lovely pet, which loves lying at the sun and taking naps on an armchair. It was not long ago when cats served an important function in every household, especially in the country. Cat is a predator that normally feeds on mice, moles and other pests, which make lives of people who occupy themselves with farming or growing crops difficult. In this context, the cat is perceived as a useful animal, as it hunts rodents and sometimes larger insects that endanger crops or the goods that have already been harvested. Cats that live in the countryside quite often give birth to their kittens in a barn and it is the place where they start learning how to hunt mice. For that reason the view of kittens lurking in hay or straw in nothing unusual.
