Where do cats get their eye color?

A cat's eye color is determined by the amount and distribution of melanin, a pigment that also contributes to skin and hair color. Here's how it works:

* Genes: Eye color is primarily determined by genes, specifically those involved in melanin production.

* Melanin Production: Two types of melanin, eumelanin (brown/black) and phaeomelanin (yellow/red), are responsible for eye color.

* More Eumelanin: Cats with more eumelanin will have darker eye colors, like brown, black, or green.

* More Phaeomelanin: Cats with more phaeomelanin will have lighter eye colors, like yellow or orange.

* Distribution of Melanin: The distribution of melanin in the iris also plays a role.

* Genetics and Breed: Specific breeds of cats are known for having certain eye colors. For example, Siamese cats often have blue eyes.

Fun Fact: A cat's eye color can actually change slightly throughout their life, particularly during kittenhood. This is because the amount of melanin in the iris can continue to develop.

Here's a quick summary:

* More eumelanin = darker eyes

* More phaeomelanin = lighter eyes

* Genetics and breed play a significant role

* Eye color can change slightly throughout life
