Cat ears are pretty amazing. There are 32 muscles in each ear, nearly twice as many as most dogs, and these allow cats to move their ears independently of one another. Cat ears are also specifically designed to funnel sound–ideal for locating prey. Cats can hear an entire octave and a half higher than humans and an octave higher than dogs. To ...
Jan 3, 2022 · The outer ear consists of the ear flap (also called the pinna), which is usually upright in cats with the exception of specific breeds whose ears are folded over. The ear flap funnels sound into the ear canal. Unlike humans that have a short ear canal, dogs and cats have a long narrow ear canal that makes an almost 90-degree bend as it travels ...

The primary function of the ear flap is to help cats detect sounds from their environment. By moving the ear flap towards the source of a sound, cats can better determine the location and distance of the sound. This ability is especially important for hunting, as cats are able to pinpoint the location of prey based solely on sound.
Ear hematoma. An ear hematoma (also known as aural hematoma) is a localised collection of clotted blood from broken blood vessels on the ear flap (pinna). This hematoma trapped between the skin and the cartilage of the ear. When the cat scratches or shakes it’s head it eventually causes a blood vessel to rupture, resulting in a hematoma.
It consists of the outer, middle, and inner ear. The outer ear includes the pinna (the part you see that is made of cartilage and covered by skin, fur, or hair) and the ear canal. The pinna is shaped to capture sound waves and funnel them through the ear canal to the eardrum. In cats, the pinnae are mobile and can move independently of each other.
Periodic pinnal alopecia causes patchy or complete hair loss on both pinna (ear flaps) of Siamese cats. Treatment is not necessary. Pattern baldness can affect only the pinna of young dogs and cats. Medications used to treat baldness in dogs and people should not be used on cats, because it has caused the death of at least two cats.
Before we can understand the purpose of the extra ear flap, it’s important to know the basic structure of a cat’s ear. A cat’s ear is made up of three parts: the outer ear, middle ear, and inner ear. The outer ear includes the pinna and ear canal, which are responsible for capturing sound waves and directing them towards the eardrum.
