Our friend, Eric, has been surmising about Cat Colorization.
“Siamese trait (the dark pigment on the nose, ears, tail, and feet ["points"]) is temperature-sensitive. The points tend to be colder and so the hair grows out dark. According to Jennifer Gates, who first told me about this, if you shave the fur of a Siamese, the first resulting coat in the area will grow in dark.”
….and from a reference to the Cat Fanciers site:
” Eye color is genetically related to coat color.
- Pointed cats always have blue eyes.
- White cats, and cats with a lot of white markings, can have:
- blue eyes
- green, gold, or copper eyes
- or “odd-eyes” (one blue eye and one green or gold eye)!
- Other cats can only have green, gold, or copper eyes, not blue eyes.
The most common eye colors are in the middle of the eye color
spectrum (greenish-yellow to gold). The colors at the ends of the
eye color spectrum (deep green or brilliant copper) are usually
seen only in purebreds who have been selectively bred for extreme
eye color, but they may sometimes appear in non-purebreds.”
