Key Takeaways

  • Loss of fur in cats can be due to anxiety, stress, hyperthyroidism, allergies, ringworm and mange.
  • Hyperthyroidism, seborrhea and diabetes mellitus can cause a cat to have oily fur.
  • Cat dandruff may be caused by skin mites, ringworm, diabetes mellitus, seborrhea and dry winter air.
  • Over-bathing or over-brushing your cat can make coat conditions worse.
  • Fur conditions are often due to underlying conditions, so see your vet if the conditions persist.

A cat’s coat is its fur and pride – felines spend hours every day grooming themselves. Some common illnesses in cats can cause painful or unpleasant symptoms that result in fur loss, changes in fur texture, or dandruff. Here’s a quick guide to abnormal coat symptoms in cats and their potential causes.

Cat Hair Loss

Unless your cat is a hairless breed, chances are you’ll be able to notice if your pet is experiencing any fur loss, officially known as alopecia in cats. The baldness can be partial or complete, random or in a pattern, and occur fast or slow. The following conditions all list fur loss as a symptom:

  • Anxiety disorders and stress can cause a cat to over-groom.
  • Hyperthyroidism has the side effect of alopecia.
  • Food allergies and environmental allergies may also cause excessive itching, which can lead to fur loss.
  • Ringworm, a parasitic fungal infection, has fur loss in a circular pattern as a primary symptom.
  • Mange is a condition caused by mites; cats suffering from it frequently experience alopecia.

Treatment: Make an appointment with your vet; all of the above medical conditions require medications prescribed by a veterinarian to treat.

Oily or Greasy Fur in Cats

Senior cats can develop oily fur from lack of grooming if they have a painful joint condition like arthritis. (

As a cat ages, grooming can become difficult due to joint conditions like osteoarthritis and hip dysplasia. Senior cats sometimes lose interest in grooming themselves as well. Fur can change in texture and become greasy or oily, often appearing spiky or clumped together. This is due to an increase or lack of distribution of the natural oils in the cat’s fur. Conditions like the following can cause this change:

  • Hyperthyroidism causes hormone imbalances; this can change your pet’s fur texture.
  • Seborrhea is a skin condition caused by some parasites, dietary deficiencies, or allergies and may also be genetic.
  • Diabetes mellitus can also be a culprit.

Treatment: If your cat’s condition is caused by difficulty grooming, try brushing your cat with a flat slicker brush. Bathing your pet with a gentle shampoo monthly may also help. However, if your cat is young or is still able to groom regularly, see your veterinarian for treatment of an underlying disease.

Cat Dandruff

Cat dandruff is more easily visible on darker felines and is more of a cosmetic issue. (

This unsightly symptom is caused by an excess of dead skin being shed. It is often visible as small white flakes on the animal’s fur. While not a problem on its own, dandruff in cats can be unpleasant to touch and typically indicates an underlying medical condition, like one of the following, that requires veterinary treatment:

  • Cheyletillosis, a skin mite condition, may cause dandruff as the mite moves under the animal’s skin.
  • Ringworm parasites can cause visibly flaky skin.
  • Diabetes mellitus causes hormone fluctuations that can affect skin dryness and coat texture.
  • Seborrhea may explain dandruff as well as oily coats.
  • Winter conditions are dry; forced air can dehydrate an animal’s skin, leading to mild dandruff.

Treatment: At-home treatment for mild dandruff can include installing a humidifier in the winter months. Adding omega-3 fatty acid supplements to your cat’s diet may also help. (Always consult a veterinarian before giving your pet any medications or supplements!) If your cat is suffering from severe dandruff or multiple skin-related symptoms, it’s time to visit the vet. Medicated cat dandruff shampoo may be prescribed to treat seborrhea or other chronic skin irritation.

Conditions affecting your cat’s fur are often symptoms of an underlying problem. If the symptoms persist, see your vet. Don’t over-bathe or -brush your pet; this can affect oil gland levels and only make your cat’s coat worse! With treatment, coat issues will resolve, and your pet can groom himself with pride.
