Got a Flaky Kitty? How to Treat Dandruff on Your Cat’s Back Near the Tail

What is Feline Dandruff?

Feline dandruff, sometimes called “flaky skin disease”, refers to the condition in cats where there is excessive shedding and flaking of dead skin cells. It leads to white flakes and crusty patches on a cat’s skin, similar to dandruff in humans (1).

Dandruff in cats is caused by excessively dry, flaky skin. The dry skin scales overproduce and are shed in large flakes or crusts. This can occur anywhere on a cat’s body, but is most commonly seen along the back, near the base of the tail (2). The flakes may be small and isolated or large, greasy sheets of skin.

While mild dandruff is normal in cats as they regularly shed dead skin cells, abnormal or excessive flaking could indicate an underlying medical issue. It’s important to determine the cause of feline dandruff through proper diagnosis by a veterinarian.

In summary, feline dandruff refers to flaky, crusty patches of skin resulting from excessively dry skin cells shedding. It’s most noticeable along the cat’s back near the tail. While mild dandruff is normal, excessive flaking may signal a medical problem requiring treatment.

Causes of Feline Dandruff

There are several potential causes of dandruff in cats:

Dry air is a common cause of dandruff in cats. Low humidity can cause the skin to become excessively dry and flaky. This is especially common in the winter when indoor heating systems create very dry air (source).

Allergies are another frequent cause of feline dandruff. Cats can develop allergic reactions to things like food, flea bites, pollen, or household products. These allergies can cause skin irritation and flaking (source).

Stress can also trigger dandruff in cats. Stressors like changes in routine, a new pet or home, or anxiety can cause increased scratching and skin irritation. This can disturb the skin’s protective oils leading to flaking (source).

Parasites like fleas or mange mites can cause irritation, scratching, and flaking of the skin. Parasites disrupt the skin which can manifest as dandruff (source).

Signs of Dandruff in Cats

The most common signs of dandruff in cats include flaky, dry skin that appears as white flakes on the skin, fur, or bedding. Cat dandruff is often accompanied by itching and scratching as the flaky skin can be quite irritating for cats.

Excessive scratching due to itchy, flaky skin can lead to hair loss and patches of baldness. The skin may also become red and inflamed from all the scratching. Dandruff typically occurs along the back, near the base of the tail, on the belly, and along the legs where cats can easily scratch themselves.

Diagnosing Dandruff

A veterinarian will perform a thorough exam to diagnose dandruff in cats. They will take a detailed history of the cat’s health and symptoms, followed by a complete physical exam. The vet will check the cat’s skin and coat all over its body, looking closely for signs of flaking, redness, and irritation. They may perform a skin scraping and microscope exam to check for ringworm fungi or mites.

The vet may recommend allergy testing, since allergies are a common cause of feline dandruff. This can include a blood test or intradermal skin testing to check for allergic reactions to foods, pollens, molds and other environmental allergens. Skin scrapings may also be taken and examined under the microscope to check for ringworm fungi or mites like cheyletiella or demodex mites.

Diagnostic tests like fungal cultures, skin biopsies or tape preps may be recommended. Your vet will diagnose the underlying cause based on your cat’s history, exam findings and diagnostic test results. With an accurate diagnosis, they can provide the right treatment plan to relieve your cat’s flaky, irritated skin.




Anti-dandruff shampoos designed specifically for cats can help relieve dandruff and soothe itchy skin. When bathing your cat, focus on lathering the shampoo into the coat and really massaging it down to the skin for several minutes before rinsing. This helps the active ingredients penetrate the skin. Some veterinarian-recommended anti-dandruff shampoos for cats include Burt’s Bees Oatmeal Shampoo, Veterinary Formula Clinical Care Antiparasitic & Antiseborrheic Medicated Shampoo, and SynergyLabs Richard’s Organics Medicated Shampoo.

Treating Dandruff in Cats

In addition to shampoos, dietary supplements can help improve skin and coat health from the inside out. Supplements containing omega-3 fatty acids help reduce inflammation and moisturize the skin. A vet may recommend supplements like Nutramax Proviable-HC or Grizzly Krill Oil. It’s important to consult your vet before giving any supplements.

If allergies are the underlying cause of dandruff, your vet may prescribe allergy medications like Apoquel or Cytopoint. These can help stop the itch-scratch cycle and allow the skin to heal. Antiparasitic medication may also be prescribed if mites or other parasites are responsible for the dandruff.

Home Remedies

There are some simple home remedies that can help treat and prevent dandruff in cats:

Brushing with a soft brush – Regularly brushing your cat’s coat with a very soft brush can help remove dead skin cells and distribute natural oils from their skin. Be extremely gentle and do not brush areas that are irritated or inflamed. Brushing helps stimulate blood circulation to promote healthy skin.[1]

Omega fatty acid supplements – Adding an omega-3 or omega-6 fatty acid supplement to your cat’s diet can help improve skin and coat health. Fatty acids like fish oil and evening primrose oil support skin hydration and reduce inflammation and dryness. Always consult your vet before giving supplements.[2]

Humidifiers – Using humidifiers around your home can add moisture to the air and prevent your cat’s skin from drying out. Keep the humidity around 30-50%. Make sure your cat has access to the humidified rooms.

Preventing Dandruff

There are several steps you can take to help prevent dandruff in your cat:

Regular grooming is important to keep your cat’s skin and coat healthy. Gently brush your cat daily or a few times a week to remove dead skin cells and distribute natural oils throughout their fur. Use a soft bristle brush made for cats. Brushing also stimulates circulation which can improve skin health. See tips for grooming a cat with dandruff at this source: [url1]

Try to identify and reduce potential sources of stress for your cat. Stress can negatively impact skin and coat health. Make sure your cat has a quiet place to retreat to, stick to a consistent routine, use pheromone diffusers, and watch their body language for signs of stress.

Controlling fleas is essential. Flea bites can cause skin irritation, inflammation and exacerbate dandruff. Use a veterinarian-recommended flea prevention medication year round.

When bathing your cat, use a moisturizing shampoo formulated for cats that contains oatmeal or essential fatty acids. These ingredients can help soothe dry, itchy skin. Avoid over-bathing which can strip natural oils. Follow directions and only bathe when necessary.

With some simple preventative measures, you can help keep your cat’s skin healthy and free of flaky, irritated dandruff.

When to See a Vet

Take your cat to the vet if their dandruff becomes severe or is accompanied by other concerning symptoms. Signs that warrant a veterinary visit include:

  • Severe flaking and itching – Excessive dandruff that causes constant scratching or discomfort indicates an underlying issue needing treatment.
  • Hair loss – Patchy hair loss along with dandruff may point to skin infections or parasites.
  • Red, inflamed skin – Dandruff accompanied by irritated, red skin could mean your cat has an allergic reaction or underlying skin condition.

While mild dandruff can often be managed at home, severe or worsening symptoms require a vet’s oversight. The vet will examine your cat and determine the cause of their dandruff. They can provide prescription shampoos, medications, or other targeted treatments for the root cause. Addressing severe dandruff promptly under veterinary care can help relieve your cat’s discomfort and prevent complications like infections or permanent hair loss.

Don’t hesitate to book an appointment if your cat’s flaky skin becomes a major concern. Your vet can get your cat the specific treatment they need for a healthy, flake-free coat.

Outlook for Cats with Dandruff

With proper treatment, the outlook for cats with dandruff is generally good. In many cases, dandruff can be easily managed with at-home remedies, medicated shampoos, dietary changes, or treating any underlying conditions. According to WebMD, most cats respond well to treatment and dandruff symptoms can be kept under control.

However, dandruff may come and go over a cat’s lifetime. It can be a chronic condition requiring ongoing care, especially if the underlying cause cannot be determined or resolved. Cats prone to dandruff may need periodic medicated baths and routine grooming. Preventative measures like diet and supplements may also be necessary long-term.

For severe or recurring cases of dandruff, a veterinary dermatologist may be needed to fully diagnose and treat the condition. With their help, most cats can achieve complete remission or have only minor flare-ups of dandruff. So while dandruff may not be permanently cured in some cats, it can often be well-managed with attentive, proactive care from pet owners.

Key Takeaways
