Final answer:
White cats are predisposed to developing Squamous cell carcinoma, the second most common skin cancer, which affects the squamous cells of the epidermis and can spread if untreated.
Step-by-step explanation:
White cats or cats with areas of white fur are predisposed to developing Squamous cell carcinoma (SCC). This is the second most common type of skin cancer and can metastasize if not treated in time. Squamous cell carcinoma affects the keratin-producing cells located in the squamous layer of the epidermis. White fur lacks pigment which normally provides protection from the sun's harmful ultraviolet rays, thus making these areas more susceptible to sun damage and the development of SCC. Routine check-ups and protecting white cats from excessive sun exposure are useful preventive measures.
