Research overview: fur waterproofing, sebaceous oils, and coat maintenance

A cat keeps its coat functional through maintenance, and this overview reviews waterproofing and coat care. Sebaceous glands coat the hairs with oils that help repel water and keep the fur in condition, and grooming distributes these oils, removes debris, and maintains the coat insulating and protective properties. A well-maintained coat resists wetting and matting. Researchers study coat maintenance through skin and grooming physiology. Why it matters: coat upkeep is essential to the many functions of fur, from insulation to protection, and grooming is the behaviour that sustains it. Understanding the role of natural oils and grooming explains why a healthy coat looks and performs as it does, and why poor grooming, illness, or skin problems that disrupt this maintenance can compromise the fur ability to insulate and shield the cat.
