Blue and white are evenly distributed, especially on the cat's head. The two colors should be clear and bright, and it is not good to have mixed colors. In the cat's nose and mouth, it is more beautiful to distribute colors in a regular pattern. The one who looks good is probably a pink neck, with a straight face and a lot of hair.
The external ear includes auricle and ear canal. The shape of auricle can capture sound waves and transmit them to the eardrum through the ear canal. The auricles of cats can move independently of each other. Turning the ear to the sound source will improve its hearing sensitivity 15-20%.
