A rare predominantly black cat with odd eyes. The odd-eyed colouring is caused when either the epistatic (recessive) white gene or dominant white (which masks any other colour genes and turns a cat completely solid white) [3] or the white spotting gene (which is the gene responsible for bicolour coats) [4] prevents melanin granules from reaching one eye during development, resulting in a cat ...
Anisocoria is a common condition, defined by a diameter difference of 0.4 mm or more between the sizes of the pupils of the eyes. [2] Anisocoria has various causes: [3] Physiological anisocoria: About 20% of the population has a slight
Domestic cat with complete heterochromia, also referred to as an odd-eyed cat. Eye color, specifically the color of the irises, is determined primarily by the concentration and distribution of melanin. Although the processes determining eye color are not fully understood, it is known that inherited eye color is determined by multiple genes ...
Cats will adjust their eyes during the day, allowing less light to filter in, while their pupils will expand at night to allow for more light, Purina reports. Feline eyes also have more "rods ...
Deafness can occur in white cats with yellow, green or blue irises, although it is mostly likely in white cats with blue irises. [4] In white cats with one blue eye and one eye of a different color (odd-eyed cats), deafness is more likely to affect the ear on the blue-eyed side. [1] Approximately 50% of white cats have one or two blue eyes. [5]
The large ears, eyes, and many vibrissae (whiskers) of the cat adapt it for low-light predation. Cat senses are adaptations that allow cats to be highly efficient predators. Cats are good at detecting movement in low light, have an acute sense of hearing and smell, and their sense of touch is enhanced by long whiskers that protrude from their ...

The phenomenon of enophthalmos is seen in Horner's syndrome in cats, rats, and dogs. [5] Sometimes there is flushing on the affected side of the face due to dilation of blood vessels under the skin. The pupil's light reflex is maintained as this is controlled via the parasympathetic nervous system. [citation needed]
