What Makes a Cat White
A white coat in cats results from a dominant gene (called the W gene) that suppresses all other color pigmentation in the fur. This gene essentially masks the cat's underlying coat color genetics, which is why a white cat might be genetically any other color underneath—you'd only know if the white gene weren't present. The W gene can appear in almost any breed, meaning white cats are incredibly diverse in terms of heritage, size, and personality.
- The W gene is dominant, so only one copy is needed to produce a white coat
- White cats are not albino—albino cats lack all pigmentation including in eyes and nose
- A white cat's actual genetic color remains hidden but can emerge in kittens if both parents carry recessive genes
