Why does a cat lose its fur and weight? - briefly
A cat may lose fur and weight due to underlying health issues such as parasites, allergies, hormonal imbalances, or stress, which disrupt normal bodily functions and nutrient absorption.
Why does a cat lose its fur and weight? - in detail
Cats may experience fur loss and weight reduction due to a variety of underlying causes, ranging from medical conditions to environmental factors. One common reason is parasitic infestations, such as fleas, mites, or ticks, which can cause intense itching, leading to excessive scratching and fur loss. Additionally, these parasites can compromise the cat's overall health, resulting in weight loss due to discomfort or nutrient depletion. Hormonal imbalances, such as hyperthyroidism, are another significant factor. An overactive thyroid gland accelerates the metabolism, causing rapid weight loss despite increased appetite, and can also lead to thinning or patchy fur. Allergies, whether related to food, environmental triggers, or grooming products, can provoke skin irritation and fur loss, while the stress of chronic discomfort may contribute to weight reduction. Nutritional deficiencies are a critical consideration; a diet lacking essential vitamins, minerals, or proteins can weaken the cat's coat and lead to muscle wasting. Chronic stress or anxiety, often triggered by changes in the household, new pets, or relocation, can also manifest in over-grooming, leading to fur loss, and a reduced appetite, causing weight loss. Infections, particularly fungal infections like ringworm, can cause hair loss and secondary weight issues if the cat becomes lethargic or stops eating. Internal health problems, such as kidney disease, diabetes, or gastrointestinal disorders, often present with weight loss as a primary symptom, and the associated stress on the body can affect the quality of the coat. Aging can naturally lead to a decline in fur density and muscle mass, but sudden or severe changes should not be attributed solely to age. Lastly, poor grooming habits or underlying skin conditions, such as dermatitis or eczema, can result in patchy fur and, if left untreated, may impact the cat’s overall health and weight. Identifying the root cause requires a thorough veterinary examination, including diagnostic tests, to ensure appropriate treatment and restore the cat’s health.
