Cats have skin too! In this episode, Dr. Susan and Dr. Kelly interview Dr. Sandra Koch, Professor of Dermatology at the University of Minnesota, to discuss dermatologic diseases in cats, with a particular focus on cutaneous masses. Dr. Koch highlights the diagnostic approach to lumps and bumps in feline patients, including differentials ranging from benign cysts to malignant neoplasms. She also discusses the clinical relevance of feline perianal scent glands, which can become inflamed or obstructed, leading to dermatologic issues. The conversation concludes with an overview of common skin cancers in cats, their biological behavior, and available treatment options—underscoring that not all cutaneous neoplasms are malignant.
