Diagnose and Treat Seborrhea in Cats

In cats, seborrhea (similar to dandruff) is typically "secondary" seborrhea. That means that it indicates an underlying condition. It's a symptom rather than the disease itself. Occasionally, cats have primary seborrhea, meaning they have a genetic disposition to seborrhea without an underlying condition. However, that is rarer.[1] Therefore, you do want to treat the symptoms of the condition, but you also need to treat whatever is causing the condition.

Steps

Looking for Symptoms

  1. Check for oiliness. Cats who have seborrhea oleosa, the "oily" type of seborrhea, will often have oily skin. Their fur may even be oily. Cats who have the "dry" type of seborrhea, seborrhea sicca, will have dry skin.[2]
    • However, some cats will have a combination of the two.
  2. Watch for flaking skin. Seborrhea is basically cat dandruff. Therefore, you'll likely notice flakes of skin in the cat's fur, particularly along the back. You may also notice the flakes where the cat has been sleeping.[3]
    • The flakes are often bigger in the oily type of seborrhea than in the dry type.
  3. Give your cat a sniff. Cats with seborrhea sicca (dry type) generally will smell normal. However, cats with the oil type will usually have a bad smell to their skin. If you notice an odor coming from you cat along with the flakes, it's more likely the cat has seborrhea oleosa.[1]
  4. Notice itching. Often, cats with seborrhea will have extreme itchiness. You may notice the cat scratching more often, as it tries to flake off the dead skin. The underlying condition may also cause itchiness.[4]
  5. Pay attention to inflamed skin. Seborrhea can also lead to inflammation on the skin, making it red and swollen. If your cat's skin has lesions or redness, that could be seborrhea. Check in the cat's armpits, neck, thighs, and belly, in particular.[3]

Diagnosing Seborrhea

  1. Watch for a physical examination. The first thing the vet will do is examine your cat, looking at the problem areas. This step helps the vet determine whether the problem is seborrhea or some other skin condition.[5]
  2. Be ready for a skin scrape test. One of the primary forms of diagnosis for this condition is the vet taking a scrape of skin for examination. This test will help establish whether your cat has an underlying problem.[6]
    • A skin scrape is when the vet scrapes at the top of the skin from different areas of your cat. They may also do a skin biopsy, where the vet will take a bit more skin, though still a small amount.
    • This test can check for bacteria, parasites, and fungi.
  3. Expect blood and urine tests. While your vet doesn't need a blood test to diagnose seborrhea itself, it's important to establish your cat doesn't have an underlying problem. Some underlying conditions include hypothyroidism and/or Cushing's disease.[1]
    • The urine and blood tests will also help the vet determine whether a hormone imbalance may be the problem.

Treating Primary and Secondary Seborrhea

  1. Shampoo your cat. Shampooing your cat can help in both dry and oily cases of seborrhea. However, you'll need to use different kinds of shampoos, depending on the type. For dry seborrhea, you'll need to use a moisturizing shampoo. For oily seborrhea, you'll need to use benzoyl peroxide or coal tar. Your vet can tell you what shampoo is best, as well as how often you'll need to bathe your cat.[7]
  2. Consider a moisturizer. Moisturizing your cat's skin can provide some relief, particularly for dry seborrhea. Talk to your vet about a good moisturizer for your cat. You don't want to just slather on any lotion you have, as your cat will want to lick that off its skin.[3]
  3. Try a hypoallergenic diet. Sometimes, seborrhea is caused by allergies. Often, the allergen in question is the cat's food. Switching to a hypoallergenic cat food can help prevent allergic reactions. You may need to try a couple of foods before finding the right one.[2]
  4. Ask about supplements. Dietary supplements like omega-3 fatty acids may help your cat's condition. These supplements contribute to healthy skin and coat, which is what alleviates some of the problem. Talk to your vet about whether your cat needs a supplement or not.[5]
  5. Treat the skin infection. Infections on the skin can be what causes seborrhea. In that case, your cat may need an antibiotic or an antifungal medication to help treat the condition. This action may remove what's causing the problem.[1]
    • An oral corticosteroid can help with inflammation.[5]
  6. Treat other underlying conditions. Because seborrhea can develop from any number of conditions, treating the underlying problem can sometimes help treat the skin condition. Talk to your vet about the best plan of action if your vet finds an underlying condition.[3]
    • Some other common underlying conditions include hyperthyroidism, allergies, environmental causes, and pain in the muscles or skeleton. Because the causes are so varied, the cat needs to be diagnosed and prescribed treatment by a vet.
