An agouti dog, also called wolf sable. In dogs, the agouti gene is associated with various coat colors and patterns. [10]The alleles at the A locus are related to the production of agouti-signaling protein (ASIP) and determine whether an animal expresses an agouti appearance and, by controlling the distribution of pigment in individual hairs, what type of agouti.
Fever coat is an effect known in domestic cats, where a pregnant female cat has a fever or is stressed, causing her unborn kittens' fur to develop a silver-type color (silver-grey, cream, or reddish) rather than what the kitten's genetics would normally cause. After birth, over some weeks the silver fur is replaced naturally by fur colors ...
A cat hair showing agouti coloration A domestic rabbit with agouti coloration. Agouti is a type of fur coloration in which each hair displays two or more bands of pigmentation. [1] [2] The overall appearance of agouti fur is usually gray or dull brown, [3] although dull yellow is also possible.
The exact cause of lentigo in cats is not well understood, but it is believed to be linked to genetics. As a result, the condition is more prevalent in certain cat colors or patterns.
Cats are limited in their perception of color. Human eyes have 10 times more cone cells than feline eyes, meaning we can see a larger range of colors than cats, according to Purina.

Agouti-signaling protein is a protein that in humans is encoded by the ASIP gene. [5] [6] It is responsible for the distribution of melanin pigment in mammals.[7] [8] Agouti interacts with the melanocortin 1 receptor to determine whether the melanocyte (pigment cell) produces phaeomelanin (a red to yellow pigment), or eumelanin (a brown to black pigment). [9]
The name given to a horse's coat color depends on the color of both the points and the body. Bay horses have a reddish-brown body with black points, which include the mane, tail, lower legs, and ear rims. [1] In horses, point coloration is most often produced by the action of the agouti gene.
