Scratching That Itch. How to Help Your Cat With Dandruff on Their Back

What is Feline Dandruff?

Feline dandruff, also known as seborrhea sicca, is a condition that causes flaky, dry skin in cats (Webmd, 2022). It is characterized by white or grayish flakes of dead skin cells that shed from the cat’s skin.

Dandruff is different from other skin conditions like dry skin and seborrhea oleosa. With dandruff, the skin flakes are dry and powdery. Dry skin leads to smaller flakes that appear greasy or oily. Seborrhea oleosa causes oily, yellow scales with a foul odor (Purina, 2017).

In cats, dandruff most often occurs along the back, flanks, belly, tail, and behind the ears. These areas tend to have less oil production, making them prone to flaking (Northkennyvet, 2022). The dandruff is not usually itchy or irritating for cats.

Causes of Feline Dandruff

There are several potential causes of dandruff in cats. Some of the most common include:

Allergies – Just like humans, cats can develop allergies to things like food, plants, or other environmental allergens. These allergies can cause skin irritation that leads to flaking and dandruff. According to veterinarians, allergies are one of the leading causes of feline dandruff.

Parasites – Parasites like fleas, mites, and ringworm cause skin irritations in cats. Scratching from parasites can damage the skin and increase the occurrence of dandruff. Treating the underlying parasite infestation is key to reducing dandruff.

Nutritional deficiencies – Cats need certain fatty acids and nutrients for skin health. Not getting enough of these in the diet can cause the skin to dry out and flake. Some deficiencies seen in dandruff include fatty acids, vitamin A, and zinc.

Seasonal changes – Dry, cold winter weather can lead to flaky, irritated skin in cats. Indoor cats are also prone to dry air from heating systems which can increase dandruff.

Stress – Stress causes various body changes in cats, including increased production of cortisol and other hormones that can affect skin health and lead to dandruff according to vets. Reducing stressors in a cat’s environment is important.

Symptoms of Dandruff in Cats

Cat dandruff typically presents itself as flaky, dry skin that causes irritation. The most common symptoms of dandruff in cats include:

  • Flaky, dry skin – Small white flakes on your cat’s skin are a telltale sign of dandruff. You’ll often see them near the tail, back, stomach and legs.
  • Itchiness and scratching – The flaky, irritated skin associated with dandruff can cause your cat to scratch excessively as they try to relieve the itch.
  • Hair loss – Constant scratching and irritation can cause hair loss and bald patches.
  • Red, irritated skin – Inflammation and irritation from dandruff can lead to red, raw looking skin.
  • Crusty buildup on skin – In severe cases, the flakes can develop into crusty scabs on your cat’s skin.

If your cat is exhibiting any of these symptoms, dandruff may be the culprit. It’s important to identify and treat the cause to alleviate discomfort and prevent skin damage from constant scratching. If symptoms persist or worsen, it’s best to see a veterinarian.

Diagnosing Dandruff in Cats

Diagnosing the underlying cause of dandruff in cats starts with a thorough physical exam by a veterinarian. The vet will check for skin lesions, inflammation, parasites, and signs of infection. They may perform a skin scraping to check for external parasites like mites or fungal infections.

The vet may also recommend blood tests to check for allergies, thyroid disease, Cushing’s disease, or other systemic illnesses that could cause skin irritation and dandruff. Tests like a biochemical profile, complete blood count, and thyroid panel can help uncover underlying diseases.

In some cases, the vet may perform a biopsy of the skin to examine the tissue under a microscope. This can reveal parasitic, bacterial, or fungal infections. Biopsies can also diagnose immune-mediated skin diseases, metabolic disorders, and skin cancer.

Once the underlying cause is determined through diagnostic tests, the vet can recommend an appropriate treatment plan to relieve dandruff and skin irritation in the cat. This may include medications, antifungals, antibiotics, medicated shampoos, dietary changes, or allergen avoidance.1

Treating Dandruff in Cats

There are several treatment options available for cats suffering from dandruff and dry, flaky skin. Using the right treatments can help moisturize the skin, reduce itchiness, and control the underlying cause of the dandruff.

One of the most common treatments is to use a medicated anti-dandruff shampoo specifically formulated for cats when bathing. These shampoos contain ingredients like salicylic acid, sulfur, zinc, and antifungal agents that help exfoliate dead skin cells, reduce fungal overgrowth, and moisturize the skin. Some popular anti-dandruff shampoo brands for cats include Douxo Chlorhexidine, Vet Solutions Universal Medicated Shampoo, and Dechra DermAllay.1

For bacterial or fungal skin infections causing dandruff and flaking, vets may prescribe antibiotic or antifungal treatments like miconazole and ketoconazole. These help clear up underlying infections. Oral supplements like fish oils may also help reduce skin inflammation and itchiness.

Anti-itch sprays like Skout’s Honor Probiotic Itch Relief Spray can provide immediate relief if your cat is constantly scratching due to dandruff irritation. These contain soothing ingredients like oatmeal, aloe, and shea butter to calm irritation.

Adjusting your cat’s diet to include more omega-3 and omega-6 fatty acids can improve skin and coat health from the inside out. High quality foods or supplements with these fatty acids help skin stay hydrated and less prone to flaking.

For cats with environmental or food allergies causing skin reactions, your vet may prescribe allergy medications like Apoquel to reduce skin irritation and itchiness leading to excessive scratching and dandruff.

Using the right treatments tailored to your cat and the underlying cause of dandruff can help manage this condition and keep your cat’s skin and fur healthy.

Dietary Changes for Dandruff

Making some key dietary changes can help reduce dandruff in cats. These changes should focus on providing high quality, easily digestible nutrients that support skin and coat health.

High quality proteins like those found in meat, eggs, and fish contain amino acids that nourish the skin and hair follicles. Look for cat foods with quality protein sources like chicken, salmon, turkey, or duck as the first few ingredients. Avoid low quality proteins like by-products.

Increasing omega-3 and omega-6 fatty acids can also help with skin dryness and flaking. These healthy fats support skin hydration and elasticity. Good sources include fish oils, flaxseed, and other plant oils. Many cat foods are now formulated with added omegas.

Probiotics support digestive and immune health, which can reduce skin reactions and inflammation. Adding a cat probiotic supplement or selecting foods with added probiotics can benefit skin from the inside out.

Finally, antioxidants like vitamins A, C, and E help protect skin cells from damage. Look for whole food sources of antioxidants like fruits, vegetables, and herbs like oregano or rosemary.

Overall, selecting a high quality cat food designed for skin support is a good first step. Talk to your vet for specific diet recommendations if your cat has chronic dandruff issues.

Home Remedies for Cat Dandruff

There are several natural home remedies that can help treat dandruff in cats. Some popular home remedies include:

Coconut Oil: Coconut oil contains fatty acids that can help moisturize a cat’s dry, flaky skin. Rub a small amount of extra virgin coconut oil gently into your cat’s fur where the dandruff occurs. This helps hydrate the skin and reduce dandruff. Coconut oil can be given orally too. Add a 1/4 teaspoon to your cat’s food 1-2 times per week to improve skin health from within.

Apple Cider Vinegar: The antibacterial and antifungal properties of apple cider vinegar make it useful for treating fungal or yeast-related skin issues in pets. Mix a 50/50 solution of apple cider vinegar and water. Wet a washcloth with the solution and gently rub on areas with dandruff. Rinse afterwards. Only use this remedy 1-2 times per week maximum.

Oatmeal Baths: An oatmeal bath can soothe dry, itchy skin. Grind 1-2 cups of colloidal (finely ground) oatmeal and run a shallow bath for your cat. Gently massage the oatmeal into the coat and skin. Rinse thoroughly afterwards. Oatmeal baths help moisturize skin and remove dead skin flakes.

Aloe Vera: The soothing, anti-inflammatory properties of aloe vera gel can provide relief for flaking, irritated feline skin. Apply aloe vera gel to the affected areas, gently massaging it into the skin. Rinse after 20 minutes. Always test a small area first in case your cat has an allergic reaction.

Dietary Supplements: Supplements like fish oil, probiotics, and Vitamin E support skin and coat health in cats. Ask your veterinarian for supplement recommendations tailored to your cat’s needs. Improving your cat’s diet with more Omega-3 fatty acids can also reduce dandruff.

Preventing Cat Dandruff

There are several ways you can help prevent dandruff and other skin issues in your cat:

Regular grooming with a soft-bristle brush can help distribute natural oils from your cat’s skin and coat to moisturize the skin and reduce dandruff. Groom your cat for 5-10 minutes daily if possible.

Since stress can impact skin health, try to minimize stressful situations for your cat. Provide a comfortable home environment and stick to a predictable routine when possible.

Use flea and tick prevention as prescribed by your vet to avoid skin irritation and damage from parasites. Products like Frontline or Seresto collars can help.

Feed your cat a balanced diet rich in omega fatty acids to promote skin and coat health. Ask your vet for diet recommendations.

Allergies to pollen or other seasonal allergens can cause skin irritation and dandruff in cats. Limit your cat’s exposure to allergens and talk to your vet about medication if allergies are suspected.

When to See a Vet

You shouldn’t take your cat’s dandruff lightly. If you’ve tried over-the-counter and home remedies but your cat’s dandruff persists, it may be time to see a veterinarian.

Some signs that should prompt a visit to the veterinarian include:

  • Dandruff that doesn’t improve after 2-4 weeks of at-home treatment (https://www.purina.com/articles/cat/health/symptoms/cat-dandruff)
  • Excessive hair loss where the dandruff is located
  • Changes in your cat’s skin, such as redness, sores, or scabs
  • Signs of a skin infection, like pus, oozing, or a foul odor
  • Your cat excessively scratching, licking, or biting at their skin
  • Overall irritation or obvious discomfort

Some of the tests a vet may run include skin scrapings, tape preps, fungal cultures, or skin biopsies to determine the underlying cause. Once the cause is identified, the vet can provide an appropriate treatment plan which may include medicated shampoos, antifungal medications, antibiotics, immunosuppressive therapy, or antiparasitic drugs (https://vetmed.tamu.edu/news/pet-talk/dont-brush-off-feline-dandruff/).

Don’t delay – see a vet promptly if your cat’s dandruff is severe or not improving with home care. The sooner the underlying issue is diagnosed and treated, the sooner your cat’s skin and coat can return to normal.

Outlook for Cats with Dandruff

The outlook for cats with dandruff is often good when properly treated. In many cases, dandruff is easily managed with medications, shampoos, dietary changes, and other treatments recommended by a veterinarian (source). Dandruff may come and go seasonally, flaring up more in dry winter months and improving in warmer weather. For other cats, dandruff can be a chronic, ongoing condition that requires continued maintenance and treatment.

While simple cases of dandruff are not serious, the presence of flakes and itching can indicate an underlying medical condition. Cats with signs of skin irritation or infections along with dandruff will need further veterinary exams and testing. Proper diagnosis and treatment of any underlying disease is important. With appropriate care guided by a vet, most cats can find relief from dandruff and maintain healthier skin and coats long-term.
