What this symptom means clinically

Pigment loss is a visible color change caused by reduced melanin content or abnormal melanocyte function in the skin or mucous membranes. Pathologically, it may result from reduced melanocyte numbers, suppressed melanin synthesis, or inflammatory or immune-mediated destruction, appearing as localized or widespread lightening or complete loss of color.

🐱 In cats

In cats, pigment loss is often seen on the nose leather, lips, or edges of coat color and may relate to local skin injury, aging, or immune reactions, with characteristic locations and distribution.

🐶 In dogs

Pigment changes in dogs may be focal or linear. Some breeds have specific patterns, and local inflammation or abnormal melanin production may also cause pigment loss.
