Here's why:
* Albinism is a genetic condition where the body doesn't produce melanin, the pigment responsible for color. This results in completely white fur, pink skin, and red eyes.
* Cats with white fur and blue eyes can have other genetic conditions that affect their color and eye pigmentation.
* The most common cause of white fur and blue eyes in cats is a gene called "W." This gene can result in different levels of white fur and eye color combinations.
Here are some examples:
* Piebald: This is a common pattern with patches of white and colored fur.
* Van: This is a breed with white fur and blue eyes, but they have some pigment in their skin and can have colored patches on their head and tail.
* Heterochromia: This is a condition where the eyes are different colors. A cat with white fur and one blue eye and one green or yellow eye could be a Van or have a piebald pattern.
It's important to remember that even if a cat has white fur and blue eyes, they might not be albino. They could have a different genetic condition that affects their color and eye pigmentation.
