Has your cat been scratching and grooming herself a lot recently? Many times, kitties that start itching and licking excessively have dermatitis. There are various causes of dermatitis in cats, and they can all cause your furry friend to become extremely itchy and uncomfortable.
What is cat dermatitis? [with pictures]
Simply put, dermatitis is an inflammation of the skin. In cats, the condition presents with areas of irritated dermis. The irritation may cause rashes, patches of bumps, or scabs on your feline.
You can see examples of each form in these cat dermatitis photos.
Most commonly, food allergies, flea bites, or an environmental allergen triggers the reaction. If you think your cat has dermatitis, schedule an exam with your veterinarian. Once the doctor diagnoses the underlying cause, he’ll be able to develop an appropriate treatment plan.
Types of cat dermatitis
There are several types of cat dermatitis. Let’s look at the characteristics and symptoms of each one.
1. Miliary dermatitis
With miliary dermatitis, cats have small, crusty pustules that resemble millet seeds. This type is usually the result of an allergy, and it makes your kitty extremely itchy. Because the bumps are tiny, you may feel them under the fur before you see them. The most common areas for the pustules to appear include:
- Lower spine
- The base of the tail
2. Food allergy dermatitis
Cats with food allergies will frequently develop dermatitis. Usually, cats with sensitivity to certain foods react to a specific protein in their diet. These types of reactions can begin at any age. When a kitty develops food allergy dermatitis, she will have a rash or bumps that tend to appear around the neck and head.
3. Flea allergy dermatitis
Some cats develop a sensitivity to flea saliva. So, when they have a flea infestation, these felines will have inflamed skin and rashes wherever there are flea bites. Cat flea dermatitis is often more common in outdoor cats. Fortunately, this form of dermatitis is easy to resolve by eliminating pests. You should treat all the cats in your household with flea medications for at least three months.
4. Solar dermatitis
Solar dermatitis occurs when cats have too much sun exposure. It’s more common in felines that have pale or white skin and appears mainly on the ears, nose, and around the eyes. At first, you may notice pink, scaly areas of skin. There may also be hair loss.
As the condition progresses, the skin will become ulcerated and crusty. Take your kitty to the vet when you see signs of solar dermatitis. This condition can sometimes lead to squamous cell carcinoma if it’s left untreated.
5. Atopic dermatitis
Atopic dermatitis can arise from an inhaled allergy, a contact allergy, or an ingested allergy. When felines react to an allergen from their environment, they usually have incredibly itchy skin. The symptoms can be body-wide or localized to certain areas, including
If the irritant is in your furbaby’s environment, you may not be able to eliminate exposure. Your kitty may require medications such as antihistamines or steroids to control the symptoms.
6. Seborrheic dermatitis
With seborrheic dermatitis, cat skin will be flaky or scaly and terribly itchy. This condition can be a result of allergies, a fungal infection, skin parasites, obesity, or a hormone imbalance. In each case, the skin’s sebaceous glands produce too much sebum.
To determine the best way to treat a cat with seborrheic dermatitis, schedule a veterinary exam. Depending on the underlying cause, the doctor may prescribe:
- Medicated shampoos
- Dietary supplements like omega-3 fatty acids
7. Eosinophilic dermatitis
Some severe environmental cat allergies can trigger certain red blood cells known as eosinophils to collect on the skin. This form of dermatitis may appear as rodent ulcers, plaques, or granulomas.
Eosinophilic dermatitis can cause significant skin problems. Treatment for cats with this disease includes anti-inflammatories and antibiotics along with eliminating the allergen if you can. If the skin will not heal, surgery may be needed.
8. Malassezia dermatitis
An overgrowth of the yeast commonly found on cat skin can cause dermatitis. When felines have this type of dermatitis, the skin may be:
- Red and irritated
- Scaly or greasy
To treat this condition, your vet will recommend medicated shampoos and ointments to reduce the number of bacteria and yeast on the skin. If your cat also has a bacterial infection, he may prescribe antibiotics.
What causes dermatitis in cats?
Several things can trigger skin inflammation in felines.
- Food allergies
- Flea saliva
- Inhaled environmental allergens
- Adverse drug reaction
- Bacterial infections
- Hormone problems
- Immune disorders
The driving factor or root of most causes of dermatitis is an allergic reaction. When your kitty encounters a foreign substance or allergen, her body treats it as an invader and mounts an immune response. When the system releases immune cells known as histamines, the skin becomes inflamed.
What are the symptoms of cat dermatitis?
Because there are multiple causes of cat dermatitis, it can have a range of symptoms. However, there will always be irritated skin. As a result, you should be able to find rashes or clusters of tiny, red bumps somewhere on the skin. Other symptoms you may notice include:

- Continual scratching or grooming
- Hair pulling
- Reddened, swollen skin
- Raw skin from scratching
- Patches of thick, hardened skin
When should you call your veterinarian?
If you notice your cat licking or scratching excessively, check for a rash or clusters of red bumps. You can run your fingers through her fur or use a flea comb to look under the hair. Another place to check for signs of irritated skin is between your kitty’s toes. Any time you find signs that point to dermatitis, you should call your vet to schedule an exam. The doctor should be able to diagnose the underlying cause and develop a treatment plan.
How is dermatitis diagnosed in cats?
The way you treat your cat’s dermatitis will depend on the type and cause of the inflammation. When you take your kitty to the vet, he’ll collect a history of symptoms and conduct a physical exam. Based on the initial findings, your vet may recommend an initial treatment plan and schedule follow-up appointments to monitor your cat’s progress.
If general treatments such as medicated shampoos, antibiotics, or flea treatments don’t help to resolve your cat’s dermatitis, the vet will conduct additional diagnostic testing:
- Skin biopsies or scrapings to check for skin parasites
- Skin swabs to check for bacterial or fungal infections
- Fur plucks to check for a variety of causes
- Allergy tests with IgE immunoglobulin
