What are the diseases of cats when they lose their hair? - in detail
Hair loss in cats, also known as alopecia, can be a symptom of various underlying health conditions. One common cause is parasitic infestations, particularly fleas, mites, or ringworm. Fleas can lead to excessive scratching, which damages the hair follicles, while mites like Demodex or Cheyletiella can directly irritate the skin. Ringworm, a fungal infection, causes circular patches of hair loss and scaly skin. Allergies are another frequent trigger; cats can develop hypersensitivity to food, environmental allergens like pollen, or even certain grooming products, leading to itching and subsequent hair loss. Hormonal imbalances, such as hyperthyroidism or Cushing’s disease, can disrupt the normal hair growth cycle, resulting in thinning or bald patches. Skin infections, whether bacterial or fungal, can also cause inflammation and hair loss. Stress or anxiety may lead to over-grooming, where cats excessively lick or chew their fur, creating bald areas. Autoimmune diseases like pemphigus foliaceus can cause the immune system to attack the skin, leading to hair loss and lesions. Nutritional deficiencies, particularly a lack of essential fatty acids, proteins, or vitamins, can weaken the coat and cause shedding. Lastly, certain cancers or tumors affecting the skin or endocrine system may manifest as hair loss. Diagnosing the exact cause requires a thorough veterinary examination, including skin scrapings, blood tests, or biopsies, to determine the appropriate treatment. Early intervention is crucial to address the root cause and prevent further complications.
