Characteristics of cat ears
Usually, cats' ears are inverted triangles, and their hearing is very sensitive, and they can hear sounds between 500 Hz and 32 kHz. A small number of cats, such as blue-eyed and white cats, will suffer from deafness due to congenital reasons.
Cats have well-developed muscles in their ears, which can make many movements, and these movements will change according to the cat's mood. When a cat is nervous and afraid, its ears will tighten backwards, and when it is happy, it will stand up more relaxed.
In addition, the cat's ear has a peculiar L-shaped structure, which can effectively prevent foreign objects from falling into the cat's ear, thus effectively reducing the risk of eardrum disease or eardrum damage.
