Noticing your cat losing hair can be concerning. While some hair loss is normal, excessive shedding or bald patches often indicate underlying health issues that need attention.
Understanding Cat Hair Loss
Cats naturally shed hair, especially during seasonal changes. However, when you notice significant amounts of hair loss, bald spots, or thinning coats, it’s important to investigate the cause.
Normal vs. Abnormal Hair Loss
Abnormal hair loss signs:
- Bald patches or thinning areas
- Visible skin irritation
- Excessive scratching or licking
- Broken or chewed hairs
- Symmetrical hair loss patterns
- Skin changes (redness, scaling, darkening)
Common Causes of Cat Hair Loss
1. Fleas and Parasites
Flea allergy dermatitis is one of the most common causes of cat hair loss. Signs include intense itching (especially at tail base), hair loss around neck, tail, and hindquarters, small scabs, and secondary skin infections.
2. Allergies
Environmental allergies (dust mites, pollen, mold) and food allergies (chicken, beef, dairy, fish) can cause hair loss around face, neck, ears, along with itching and ear problems.
3. Psychogenic Alopecia
Stress and anxiety can cause excessive grooming leading to hair loss. Triggers include new pets, moving, changes in routine, multi-cat tensions, boredom, and separation anxiety.
4. Ringworm
A fungal infection causing circular patches of hair loss, red, scaly, inflamed skin, broken hairs at the edges, and mild to moderate itching. Ringworm is contagious to humans and other pets.
5. Mange (Mites)
Demodectic mange causes localized small patches of hair loss. Notoedric mange (feline scabies) causes intense itching and hair loss starting on face and ears, spreading rapidly.
6. Hormonal Imbalances
Hyperthyroidism causes hair loss (often thinning), dull, greasy coat, weight loss despite good appetite, increased thirst and urination, and hyperactivity. Cushing’s Disease causes bilateral hair loss, thin fragile skin, and pot-bellied appearance.
7. Dermatological Conditions
Feline Seborrhea causes flaky, scaly skin, greasy coat, hair loss, and foul odor. Eosinophilic Granuloma Complex causes raised, ulcerative lesions and hair loss around lesions.
8. Poor Nutrition
Inadequate diet can cause dull, thinning coat, excessive shedding, and hair loss. Low-quality foods or restrictive diets can lead to deficiencies.
