An author's observation. A hot summer day in Moscow suburbs. A Cat quietly drowses near a small house worth on an extensive country site. Her kitten plays around her. Suddenly the Cat has sharply risen, as if did not sleep, unwrapped herself and run aside into bushes by a business, fast gait. In several minutes she returned by the same gait with an alive mouse in her teeth and began to teach the kitten to hunt. How she did it, is an interesting and instructive topic, but it is already of the pedagogy area.
    Here we'll note, that Cat's activity was extremely purposeful. No doubts, no hesitations. Confidence and resoluteness, accuracy and quiet speed. It is on the one hand.
    On the other hand - she could not receive the information on the mouse by on one of physical perception channels. Sight, taste and tactile sensations are excluded with evidence. Hearing. When a cat listens, it moves its ears, directs them to the place of noise; in our case Cat's ears was quiet and directed forward, but she ran aside (and even rather back). The smell rests. And it is excluded too: when a cat sniffs, when chooses direction by smell - its behaviour happens completely: it becomes slow, cautious, alert, its shape changes.
