White cats having one blue and one other-colored eye are called "odd-eyed" and may be deaf on the same side as the blue eye. [16] This is the result of the yellow iris pigmentation rising to the surface of only one eye, as blue eyes are normal at birth before the adult pigmentation has had a chance to express itself in the eye(s).
It may be that altricial strategies in mammals, in contrast, develop in species with less migratory and more territorial lifestyles, such as Carnivorans, the mothers of which are capable of bearing a fetus in the early stages of development and focusing closely and personally upon its raising, as opposed to precocial animals which provide their ...
Binocular vision anomalies include: diplopia (double vision), visual confusion (the perception of two different images superimposed onto the same space), suppression (where the brain ignores all or part of one eye's visual field), horror fusionis (an active avoidance of fusion by eye misalignment), and anomalous retinal correspondence (where ...

“For cats, primary humans are adored, and spare humans are to be tolerated,” says the very spare human in this video. But just because you are not a cat’s favorite person doesn’t mean you ...
It is unclear why Ivy lost her eye, but cats can have the same number and types of eye problems as humans. One of my cats often walks around with one eye swollen and shut due to a birth defect ...
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 ...
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 ...
