Cats have a tapetum lucidum, which is a reflective layer behind the retina that sends light that passes through the retina back into the eye. [1] They also have a high number of rods in their retina that are sensitive to dim light. [2]
Statements that certain species of mammals are "born blind" refer to them being born with their eyes closed and their eyelids fused together; the eyes open later. One example is the rabbit . In humans the eyelids are fused for a while before birth, but open again before the normal birth time, but very premature babies are sometimes born with ...
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 ...

The tapetum lucidum, in animals that have it, can produce eyeshine, for example as seen in cat eyes at night. Red-eye effect, a reflection of red blood vessels, appears in the eyes of humans and other animals that have no tapetum lucidum, hence no eyeshine, and rarely in animals that have a tapetum lucidum. The red-eye effect is a photographic ...
