Cats
Where the skin was injured or burned, the fur has grown back white,
not grey. The cat had suffered frostbite injuries. Some dark coloured cats show white hairs in
their coat as they grow older - some follicles stop producing pigment, just as humans get
"grey" hairs. Unlike the cobweb effect (where pigment loss occurs in patches, like snowflakes
or strands of gossamer), age-related white hairs are evenly sprinkled across the body giving a
salt-and-pepper effect; there may also be greying around the muzzle. It is a normal part of
ageing although cats seem far less prone to getting grey hairs than do dogs. It should not be
confused with the white patches found in vitiligo.
SWIRLED PATTERNS AND SKUNK STRIPES
While the piebald pattern is generally fairly symmetrical until the white exceeds 60% of the
body surface, some cats exhibit a variety of swirled patterns. This may simply be due to the
