Not only does the cat hear more clearly, but its hearing frequency range is four times that of us. Therefore, cats can perceive the smallest sound within 20 meters around them. They have the super ability to recognize and perceive sound, and can determine the source of sound very accurately and quickly. Cats can smell molecules. They can perceive smells better than we can and distinguish them perfectly, and can distinguish mixed smells one by one. Because of this, cats are very picky about food and will refuse to eat certain foods because they refuse certain ingredients. Another incredible organ of the cat is the Jacobson organ, which senses through two holes in the upper jaw. This organ specialized in sensing hormones and their odors is highly developed in cats, which helps them to judge whether the final meeting is risky by sensing each other and their determination.
