Pet Cats Have Special Perceptual Abilities
Turkish Angora Cat
have quite outstanding day and night vision abilities. In bright conditions, Angora cats constrict their pupils to a line-like narrow slit to reduce damage to the retina, but this limits the breadth of their field of view. On the back of the Angora cat’s retina is a thin blue-green fluorescent-like layer (called tapetum lucidum) that enhances vision in the dark and in flashes of light. Angora cat eyes can display a variety of colors. Like most carnivores, their eyes are positioned facing forward on the face, granting a wide field of vision. Angora cats have poor recognition of the three primary colors.
If the Angora cat has only faint light here, it uses its whiskers to enhance mobility and perception. Whiskers can detect very slight air currents, helping identify obstacles when visibility is low. The circle formed by the tips of the whiskers and the connected ears exactly corresponds to the smallest space the body can pass through, enabling quick terrain assessment at night.
Angora cats have a third eyelid. When the Angora cat’s eyelid is open, the nictitating membrane slightly covers the eye from the side. If an Angora is sick, sleeping, or smiling, this eyelid partially retracts. If an Angora cat exposes its third eyelid for a long time, it indicates a need to see a veterinarian.
Almost all Angora cats have upright ears during normal times, unlike , folded ears in Angora cats are very rare; the Scottish Fold Angora cat is an example of a gene mutation. When angry or frightened, Angora cat ears droop and are accompanied by growling sounds. When listening, Angora cats rotate their ears so they can hear sounds coming from various directions.
