Senses of cat

Cats have the same 5 senses as people do but to very different degrees. Some senses are much better developed than in people.

Sight

Cats have keen vision; they can see much more detail than dogs. Concentrated in the center of the retina of the eye, a specific type of cell called a cone gives cats excellent visual acuity and binocular vision. This allows them to judge speed and distance very well, an ability that helped them survive as hunters. However, although the cone cells are also responsible for color vision, it is uncertain whether cats can see colors. Like dogs, cats also have a lot of the retinal cells called rods, which are good at collecting dim light. In fact, cats can see 6 times better in dim light than people, giving rise to the myth that cats can see in the dark. Cats also have a reflective layer called the tapetum lucidum, which magnifies incoming light and lends a characteristic blue or greenish glint to their eyes at night.

A unique feature of both canine and feline eyes is the nictitating membrane, which is also called the third eyelid. This additional eyelid is a whitish pink color and is found under the other eyelids in the inside corner (near the nose) of the eye. The third eyelid extends up when needed to protect the eyeball from scratches (such as while traveling through brush) or in response to inflammation.

Hearing

Cats are very sensitive to sound, with a range of hearing both above and below the range of frequencies that can be detected by people. They can hear better than people and even better than most dogs. Feline hearing also acts as a direction finder, which is useful for hunting purposes. Cats generally turn their heads toward the direction of the sound while listening to pinpoint the location. The ear canal of cats is deeper and more tapered than in people. This deeper canal is subject to buildup of dirt and wax that can lead to inflammation and secondary infection, although to a lesser degree than in dogs.

The semicircular canals, which are found within the inner ear, are filled with fluid and are important for maintaining balance. These are highly developed in cats, accounting for their agility and excellent sense of balance. Cats can usually determine their body position at all times and can rapidly right themselves when falling, which explains the origin of the phrase, “Cats always land on their feet.”

Smell and Taste

Cats do not rely as much on the sense of smell as some other animals. The sense of smell is less developed in cats than in dogs. Like people, cats are finicky about odors and try to cover disagreeable smells. Also like people, odor is an extremely important part of taste and enjoyment of food for cats. Cats that have lost their sense of smell due to illness (such as nasal or severe respiratory infection, nerve damage, or certain cancers) often stop eating completely.

Most cats are excited by the smell of catnip, a plant that is a member of the mint family. However, not all cats react in the same way. Some become manic, others roll and purr, others are minimally affected. This herb is harmless and can be given to your cat either directly or as part of a catnip toy or ball.
