Loss of pigment which may be temporary or permanent; usually on nose, lips, and face
Clinical signs, skin biopsy
Pigment: A substance, such as chlorophyll or melanin, that produces a characteristic color in plant or animal tissue.
Pinking Up: In a pregnant female, the changing of the color of the nipples to pink, typically occurring in cat's about three weeks after successful mating.
Pinking up: Nipples turn pink if the cat is pregnant about three weeks after mating.
Placenta: Organ that allows the exchange of oxygen, food and waste material between a mother cat and a fetus.
Pigment: coloring matter
Pinking up: primarily a British term for the characteristic coloring of the queen's nipples about three weeks after a successful mating
Pinna: the ear flap ...
Lack of pigment in the nose leather and/or paw pads in part or in total, except as allowed in the color definitions for lynx and tortie points. Crossed eyes. Visible protrusion of the cartilage at the end of the sternum under normal handling. Soft or mushy body.
The Dense pigment gene, D/d, codes for melanophilin, a protein involved in the transportation and deposition of pigment into a growing hair.
A certain pigment that is produced when hemoglobin is destroyed.
A condition in which the liver becomes inflamed ...
MELANIN - The main pigment that gives color to the skin and hair. Melanin produces eumelanin and phaeomelanin.
MITTED PATTERN - A predominantly colored cat with white limited to paws, back legs, belly, chest, and chin in most specimens. Cat is about 1/4 white.
Their color is viewed on the pigment of the skin and on the few hairs (down) they have. Perhaps their second most distinguishable feature is their huge ears, frequently more than 2 or 3 inches in height.
The semi-longhaired Somali’s coat is generally soft, but texture can vary depending on color because of the way pigment particles are shaped and distributed within the hair shaft.
The Burmese Brown coat is caused by the Burmese gene (cb), part of the albino series, which causes a reduction in the amount of pigment produced converting black into brown, and all the other colours into a paler, more delicate shade of their full colour equivalents.
Jaundice is the yellow staining of the serum or tissues, including skin and mucous membranes, caused by an excess of the bile pigment, bilirubin. Jaundice, also referred to as 'icterus,' can turn a cat's urine a bright, yellowish-orange color ('bilirubinuria').
Its short hair coat contains a mutated enzyme in its pigment that produces its cream colored torso offset by darker points at the ears, face, and toes.
Higher temperature causes the pigment to lighten. When a Siames kitten is born, the pattern is not obvious and begins show itself after a few days. Another aspect of the Siamese pattern called gene modifiers can influence the density of the pigment and can be selected by the breeder.
The nose leather should be a pinkish colour outlined in pigment or to tone with the points.
2. Markings in kittens are not as well defined.
3. A ringed tail is desirable but a solid top-tail, ringed on the underside, is not a fault.
A study at Vanderbilt University found that Siamese cats frequently had less sharp vision than other cats, which corresponded to the lower levels of pigment in their eye color. For this reason, Siamese cats tend to be less active at night.
Signs of contact allergens: dermatitis, pigmentary changes or skin eruptions. Most noticable on the chin, ears, inner thighs, abdomen, underside of the tail, armpits and around the anus.
Skin patch tests are used to determine cause of contact allergies.
A small percentage of white cats are deaf. The gene for white is 100% effective in preventing the formation of pigment in fur and the hearing ability of any given white cat depends on whether it has one or two genes for white and their interaction with other genes.
protrusion of the nictitating membrane
pigmented spots in the eye
strongly weeping and/or inflamed eyes
clouded eyes ...
Unlike the blue eyes seen linked to the genes in bicolor cats and cats with point coloration, both of which suppress pigmentation, this gene is not linked to any certain fur color or pattern, giving the opportunity to have cats with dark coats and blue eyes.
Prizes can be withheld from exhibits if they show certain defects such as oriental or British type, smallness, eyes with blue pigmentation, protuberant eyes, noticeable white hairs, either in patches or peppered through the coat, lack of weight or condition, ...
The silver colouring is the result of an inhibitor gene (I) that takes out the yellow pigment in the coat of a full colour cat.
It is also possible to produce silver snows.

My darling Cornish, Luther, has suddenly developed brown pigment spots in one eye. He is 6 years old. Does anyone know if this is harming his eye?
They are registerable in every color that a cat comes in and the color is seen in the pigment of the skin and the few hairs that they do have. One of the questions most asked is “Don’t they get cold?' Well, of course, if it is too cold for you it will be too cold for a hairless cat too.
Thought to be one of the oldest breeds, the Abyssinian has a well muscled body with a unique ticked coat resembling the wild rabbit. This appearance is effected by two or three bands of light and dark pigment on every hair.
The eyes of the Siamese cat appear red in the dark; the retinas lack pigment, and the color is provided by blood vessels. A cat is very alert to any movement, but it probably cannot distinguish color. For these reasons, it will pounce when a victim moves but may not attack prey that remains still.
The skin temperature of the body’s extremities is a few degrees cooler than the rest of the body, and therefore attracts more pigmentation. The cooler the environment, the darker the color becomes.
It is acceptable for them to have short, tightly packed soft hair on their ears, muzzle, nose, feet, tail base and on the tip of their tail. Every color in the rainbow of cat colors is acceptable. The color is visible in the skin pigment and on the small amount of hair they do have.
