Squamous cell carcinoma is common in white cats, affecting sun-exposed skin of ears, nose, and eyelids. Early recognition and treatment significantly improve welfare outcomes.
White cats are at high risk of solar-induced SCC due to lack of pigmentation in sun-exposed skin areas. The development is insidious — years of UV damage accumulate through sunbathing before pre-cancerous and then cancerous changes become apparent. Early lesions show as reddened, thickened, or crusted areas on ear tips, the nose, or eyelids. These lesions are initially uncomfortable; as SCC develops, they become painful, ulcerative, and invasive.
Prevention through behavioral management — restricting outdoor access during peak sun hours, providing sun shelter, and applying SPF50+ pet-safe sunscreen to vulnerable areas — prevents the solar damage that drives SCC development. This welfare-positive approach is far preferable to treating advanced disease.
