White Cats

White cats are captivating felines with a striking appearance that is a result of a specific genetic trait. Their pure white coats are not a color but rather a lack of any pigment, which can have interesting implications for their health.

The Genetics of White Cats

A white cat’s coat is determined by the W gene (dominant white). This gene is dominant and acts as an “epistatic” gene, meaning it can mask other coat color genes. Even if a cat inherits genes for a black, orange, or tabby coat, the dominant white gene will prevent any pigment from being expressed in their fur, resulting in a pure white coat.

Potential Health Issues

The gene for a white coat is sometimes linked to certain health conditions, particularly deafness. This is especially true for white cats with blue eyes.

• Deafness: The W gene can cause the degeneration of the cochlea in the inner ear, leading to congenital deafness. This is more common in white cats with one or two blue eyes. Cats with one blue eye may be deaf in the ear on the same side as the blue eye.
• Sunburn and Skin Cancer: Since white cats lack melanin, which protects against UV radiation, they are more susceptible to sunburn and the development of skin cancer, particularly on their ears and nose.

Personality

As with any cat, personality is individual. However, many white cat owners describe their companions as being gentle, quiet, and serene. They can also be playful and affectionate, just like any other cat.
