Cat Dandruff: Is It Something to Worry About?

Is cat dandruff an issue or not? Here's the scoop on why cat dandruff happens and how to handle dandruff in cats.


I have a 4-year-old indoor Himalayan/tabby mix who has cat dandruff on the back half of the top of her back. I was wondering what may be the cause of the cat dandruff and what treatment would help. She has had it since she was a kitten, but it pretty much only becomes obvious when I brush her or take her to the vet. My vet has seen it before, so it may not be something to even be concerned about? -Amber

First, what is cat dandruff?

Given that veterinary medicine even has a term to describe freckles in ginger cats — lentigo simplex — it should not surprise the reader that veterinary medicine has a term to describe severe dandruff: seborrheic dermatitis. I prefer to call it dandruff.

Is cat dandruff common? Why does cat dandruff happen?

Yes, cat dandruff is common. It occurs most frequently exactly where you have described: on the back, closer to the tail than to the head. This cat dandruff may be accompanied by greasy hair.

Most of the time, dandruff, even when severe, is not representative of a disease. However, some skin parasites (particularly one called Demodex) and fungal infections (such as ringworm) can lead to cat dandruff. So can glandular disorders such as hyperthyroidism, allergies to fleas or food, and even severe problems such as lymphoma. Some cats appear to respond to dermatological insults (such as exposure to chemical irritants) by producing dandruff.

What should you do about cat dandruff?

To be sure, you did the right thing by taking your cat to the vet. I hope that she did the appropriate tests to rule out those more serious problems. If she did, it is safe to say that your cat has a good, old-fashioned case of feline dandruff. That means two things. First, the problem will be hard to solve. Second, the problem isn’t a problem and it doesn’t need to be solved.

Cat dandruff is, in my experience, hard to treat. Some vets have touted success with dietary supplements such as omega-3 fatty acids. Others recommend special shampoos or spot-on therapies (specifically, I have seen some vets recommend Douxo Spot On or Alloderm). A few owners have reported success after changing their cats’ diets.

However, most people who have cats with dandruff end up frustrated. In my experience, the cat dandruff “problem” does not improve no matter what is done.

The final word on cat dandruff

I put “problem” in quotes for a reason. If your vet has ruled out serious skin disease, and your cat is not suffering from itching, hair loss or pain, then as far as your cat is concerned, there is no problem. Cats, unlike humans, don’t worry about first impressions. They don’t obsess in the mirror.

Since the dandruff isn’t bothering your cat, I recommend that you not let it bother you. Why risk gastrointestinal upset from a diet change, or an adverse reaction to a shampoo? The problem isn’t really a problem, so why not do nothing? Veterinary medicine has a fancy term for this as well: benign neglect.

  4. Dandruff is never “not a problem” and to compare it to the vanity aspect of human dandruff is obnoxious. Simple fact: dandruff is not normal.

    First order of business is to provide your cat with a biologically appropriate diet, and no, kibble is nothing that should ever be described as biological or appropriate. Best option is a raw homemade diet, or slightly cooked if your cat is disinterested in raw. Give them time to recognize that the junk food previously provided isn’t coming back.

    Second, have your cat tested for any illness that might have a hand in causing the dandruff. Dandruff is the symptom of a bigger issue and just because your cat isn’t verbalizing his/her discomfort, doesn’t mean they aren’t unwell and should suffer in silence. Can you imagine being ill and ALWAYS itchy?

    Finally, in addition to the above, treat topically with a natural food grade moisturizer such as coconut or safflower oil. Before applying, be sure to brush your cat regularly and often to encourage circulation and to remove flakes.

    When bathing is necessary, but not an option, fill a bucket or bowl with lukewarm water + a squirt of Dr. Bronner’s soap. Use a dampened washcloth to “pet” your cat.

    1. You shouldn’t blame on your cat if it’s your flakes god I hate people who do that. I’m huge pet lover and love and care for my furrybaby never ever I blame them… it’s your fault not your cat… you”……..&@@@@@@@@@@

  6. My 4yr old Calico-Tortie has always had dandruff about 2″ from her tail to the base of the tail, her son, now 2, who has much thicker & longer fur also has dandruff . It seems to be worse when they are shedding (post winter coats & post summer coats). They have a mainly dry diet, extremely glossy coats, are full of life & very happy cats. They get the odd treat of oily fish when I can afford it. But they have a mix of no grain kibbles, Royal Canin & Concept for Life. They also have bedtime treats of meaty chews & some “biscuit” kibbles which they love.
    I get most of their food from Zooplus as their prices tend to be cheaper. The Vet has seen their dandruff & is not considered to be “An issue” or “a problem” – I have a cloth (Microfibre) that after grooming I just wipe over their fur & it picks up the dandruff. Since they are incredibly healthy with coats you can almost see yourself in I don’t see the dandruff as an issue.

  7. I have been using an organic healing salve of olive oil, coconut oil, shey butter and propolis. My cats skin is healing! Large flakes of the dried yellow skin is peeling off. He seems so much happier, as I think it itched before. There seems to be many layers that need to shed off. Some spots are flake free and now are soft and resoved. It’s been two weeks of this treatment and looks like another two weeks might reslove it completly.

    1. Could you tell me please how much of each ingredient you are using and the method in which you apply it? Also, how often?

    2. That’s really good I’m happy for you! What is your cats diet? I want to know because two of our cats have dandruff on the backs of them and I’m sort of worried. ????

    I give my cats raw coconut oil – they love it and will lick it off the spoon. This gives them double protection: hairballs and some additional oil that helps from the inside out.
