Siamese cats change color due to a genetic mutation in the "temperature-sensitive albino" gene.
The ambient temperature affects Siamese cats' coat color, with colder environments darkening the extremities and warmer climates lightening the overall fur.
As Siamese cats age, their coat darkens from a light beige or cream color at birth to deeper points in cooler areas by around 2 years old.
Health conditions like fevers or thyroid disorders can cause temporary changes in a Siamese cat's coat colour.
Poor nutrition or nutrient deficiencies can dull a Siamese cat's coat.
Sunlight exposure can darken a Siamese cat's points (ears, paws, face, tail), while indoor cats may retain lighter coloration.
Seasonal temperature changes cause Siamese cats' points to darken in winter and lighten in summer as body temperature fluctuates.
