It is believed that cats are mystical creatures that are given to us from above to harmonize family relationships and home. From here our inexplicable attachment to them, despite the fact that they themselves remain independent and not subject to our influence.
What do our scientists think about this? For example, american researchers sequenced (sequencing – definition sequences in the structure of DNA) genomes of a domestic cat, two species of wild cats, dogs, tigers and humans. It turned out that domestic cats, unlike other mammals, possess genes, which turn them into hyper predators with excellent vision and hearing, unsurpassed patience and perseverance, amazing plasticity and swiftness. And at the same time, domestic cats have an increased number of cells of the so-called nerve crest making them an ideal creature for domestication. Apparently in antiquity cat was chosen as a pet absolutely not by chance.
American biologists at Stanford University in their research went even further and even found a unicellular parasite Toxoplasma gondii, allegedly controlled by domestic cats, infecting them other animals. After that, all infected are firmly become attached to the carrier of bacteria. If you watched a movie either read the book “Perfumer”, you will easily understand what kind of mechanism.
Thanks to the bacteria Toxoplasma gondii, the cat even infects its victims – mice or rats, and they obediently rush to her paws, losing all fear of this predator. Parasite Toxoplasma gondii is not safe for humans, in some cases it may cause a real mental disorder, a kind of insanity motivated by love for cats. Remember the half-crazy old women who bring in their apartment fifty cats, losing all real idea of what they are doing.
However, like all bacteria, Toxoplasma gondii acts very selectively. Some people literally go crazy with cats, others him completely indifferent. Even in the same family, love for this not everyone has the same pet.
As for bacteria, everyone understands and believes as he wants, but even that the fact that domestic cats lived with a man another eight thousand years before AD, says a lot. For such a long time, man and the cat just could not help but be so close that exist can’t live without each other. So it is, at least it concerns the cats themselves. However, man, can he live without this funny, cute and so affectionate purr?
