Explore the secrets of cat’s ears

       The cat’s hearing is very sensitive, which is mainly determined by the specific anatomy and physiology of its auditory organs. The ear is an auditory organ, which consists of the outer ear, the middle ear and the inner ear. Cats can hear sounds from 30 Hz to 45 kHz, while humans can only hear sounds from 20 Hz to 20 kHz. The cat’s function of locating sound is also better than that of human beings. Its two ears are like radar antennas, which can rotate with the sound direction, and can distinguish two similar sounds at a distance of 15-29 meters and a distance of about 1 meter. In addition, the balance function of the cat’s inner ear is far better than that of the human inner ear. It is very rare to see cats vomiting due to carsickness and seasickness when they travel by car, ship or plane. But cats, like humans, lose their hearing as they get older. In addition, cats’ ears have about 20 muscles more than humans, so they can not only hear better than humans, but also turn their ears to capture the location of sound. Although cats have excellent hearing, some cats are born without hearing. This is a symptom caused by genetic defects. It is said that white cats with blue eyes are particularly prone to this situation. However, cats with strong vitality, even if they are deaf, can quickly adapt to the environment. However, cats, like other animals, have congenital and postnatal deafness. It is generally believed that cats with blue eyes can’t hear sound. In fact, this is a misunderstanding. For example, Siamese cats are mostly blue eyed, but the proportion of deafness is very small. However, some people have counted that white hair and blue eye cats have a higher proportion of hearing loss, which may be related to genetic factors, such as congenital deafness The occurrence of syndrome is mainly caused by genetic abnormalities on chromosomes, which lead to deafness due to incomplete or undeveloped organs such as Corti’s organ and spiral ganglion of the cochlea. However, congenital deafness is not really can not hear a sound, but to some sounds can be heard, only through the limbs claw meat pad to complete, not with the ear to hear. Under normal conditions, there are quite a lot of tactile sensors in the cat meat pad, which can sense the tiny vibration on the ground. Cats can use it to detect the activities of rats in underground rat holes. Deaf cats have more receptors in their meat pads, so even if some sounds make the ground vibrate slightly, they can be “heard” by cats. In addition, deafness rarely affects the balance function of cats. In this way, combined with normal vision, deaf cats can grow and develop very healthily.
