Cats
White
spots appear on the coat; these become more extensive with age until the cat has a white lace
pattern on the black fur. Ultimately the cat may go completely white or be left with
diminishing isolated patches of colour. This condition has been seen in black leopards
("cobweb panthers"), humans, dogs and other animals. This must not be confused with the
normal sprinkling of isolated white hairs which appear in a cat's fur during its lifetime.
"Leukotrichia" is a generic term. Acommon term is "piebaldism" because it causes white
patches in the skin and fur. It is an "aquired depigmentation" that occurs during the cat's
lifetime, is usually progressive and may be triggered by illness or environmental factors.
Ultimately, a cat with leukoderma may become almost entirely white. Antibodies are formed
against the pigment-producing melanocytes. The melanocytes are destroyed leading to the
white areas
