When investigating cat skin problems, start with simple explanations and then move to those that require veterinary tests (although it never hurts to visit your vet). For mild cat skin itch and flaking with no other symptoms such as pus or oozing lesions, fever or significant hair loss, try a mild non-medicated shampoo or waterless bath wash (see below for recommendations).
In terms of a cause, first suspect fleas, even if you don't find any, as an early flea infestation is hard to spot and can cause problems. Cat flea symptoms include red areas, scabs and cat hair loss. When checking for cat fleas, pay attention to areas of the body such as the spine, neck and under the chin. For fleas, you'll need to eliminate them from your cat via a herbal treatment (see below), and then use a preventative such as Frontline Plus.
If fleas are not the problem, you can try one of the medicated shampoos mentioned below. If the condition worsens, hair loss continues, you see changes in behavior, other symptoms such as pus filled pimples etc, then visit the veterinarian for some preliminary tests and evaluation (see below for tips on diagnosis).
Be sure to always check your cat for any skin lumps, bumps, scabs, red skin areas, or anything that looks abnormal.

Why It's Difficult to Recognize Cat Skin Problems
Unlike dogs, which tend to scratch at skin problems, cats are more likely to lick problem areas. This isn't that different than ordinary grooming behaviors. Instead, you'll need to look for the following signs of cat skin disease:
- grooming more often than normal, particularly in one area
- changes in behavior such as acting agitated or anxious
- twitching of the superficial back muscles
- hiding from view
- avoiding attention
Pictures and Descriptions of Common Cat Skin Problems
Use these pictures of descriptions of cat skin problems to identify or eliminate possible feline skin diseases.
Macule: A macule is a area of the skin where there is a change in color. Common causes are some type of inflammation or injury.

Papule: A papule is a type of lesion that is elevated. If it is large it is called plaque. This type of cell inflammation is commonly called a neoplasm (which refers to any type of cells, not just papules). A bigger papule is called plaque. A neoplasm can be benign (not cancer) or malignant (cancerous that spreads).

Postule: A postule is an area on the skin that is filled with pus. Pus is caused by white blood cells that are sent to kill a foreign invader such as bacteria or a fungus. The dead cells create a lump on the skin called a postule.

Vesicle: This is a lump underneath the skin that is filled with an unusual amount of fluid (called edema).

Wheal: A wheal is a raised area that tends to heal by itself in minutes or hours. It is an area with increased redness or has a pale color when compared to surrounding areas. It is also referred to as a cat hive with symptoms such as severe itching. Common causes include certain foods or drugs, infection, insect bites or allergy.

Cat atopic dermatitis in particular is the second most common cause of feline skin conditions after flea allergy (see below). Symptoms are similar to flea allergy so if you cat has been on a flea preventative, then atopy should be the next area to investigate. The condition is usually treated with a prescription steroid such as the medication prednisolone. If any skin rubbing resulted in infection, then antibiotics will be prescribed as well.

Miliary dermatitis refers to cat skin problems where scabbing lesions form in areas under the chin and neck.
Cat Miliary Dermatitis
Even a few cat fleas can result in skin problems on the back half of the body, or all over the body. Problems are also often seen above the tail. It can be difficult to find the fleas since cat fur is thick and fleas tend to hide near the skin. Even if your cat stays indoors, fleas can be brought into the house on your shoes, or the shoes of your visitors. They can also be spread by other pets. This is why all cats and pets in a home need to be on flea preventatives such as Frontline Plus® and Advantage®. Avoid off-brand products such as Pet -Armor®. Even though these have the same active ingredient as Frontline, the concentrations could be delivered in a different medium and therefore possibly be less effective (ask your veterinarian for the best product to use for your cat).
Treatment includes killing all fleas, and then using a flea preventative. During recovery, improve hair condition with a homeopathic (see bottom of page) and Omega Fish Oil Supplements.
- Ringworm: (also called dermatophytosis) Ringworm in cats is less common than cat flea allergy or atopic dermatitis. This fungus occurs in cats with inadequate immune systems, which is a particular problem in kittens whose immune systems haven't had time to develop. Cat ringworm symptoms include hair loss and crusting on the paws and face. Some cats can be carriers of the disease without showing any symptoms, which could explain why one cat in a two cat household has the disorder. Treatment options include a natural skin treatment such as Naturasil.

Symptoms of Feline Skin Disorders
Symptoms of feline skin problems include:
- Dry, flaky cat skin
- Red, irritated looking skin called skin lesions
- Loss of hair (called cat alopecia, or the result of atopy see feline skin allergies above)
- A dry, dull-looking coat
- Lumps or bumps on or under the skin
- Red patches on the skin
- Round raw lesions on the head, hips and chest called cat hot spots
- Scaly patches or scabs on the skin
- Your cat may scratch or lick her skin excessively (called pruritis)
Diagnosis of Cat Skin Problems
Your vet will examine your cat’s skin carefully as part of a complete examination. In order to properly diagnose any cats skin problems in the following order:
- Physical Examination: Some types of cat skin disease such as fleas are immediately identifiable by your vet. such as fleas.
- Skin Cytology Tests: The next most likely cause is a cat skin infection caused by bacteria. Cytology tests are used to examine skin cells in order to confirm this specific diagnosis.
- Fungal Culture Test: This test is used to detect fungal infections such as cat ringworm. Results take 2 to 3 weeks, so the test is often given at the first office visit just in case. A special lamp called a Woods Lamp is also used as an in-office diagnostic test for certain types of cat fungal skin infections.
If the fungal culture is negative, then most vets will conduct additional tests such as: - Skin biopsy: These tests look for problems such as cat skin cancer. In this test, a needle is used to remove cells from a lump to be examined by a pathologist. This can determine if a lump is cancerous or if it is just a cyst or wart.
- Food Trial: Food allergy is a common cause of allergy in cats. If this cause is suspected, then the vet will recommend a hypoallergenic diet .
- Blood and Serum tests: These tests can be used to check for infections, certain nutrient deficiencies and allergens (serum tests). Intradermal tests (skin surface tests) can also be used to test for certain allergens that are causing atopic dermatitis (skin inflammation), after other possible causes are eliminated.
Identifying Cat Skin Problems by Location on the Body
The location of the cat skin disorder can also indicate the type or problem your cat might have. For example feline skin problems on the ear can indicate mites or food allergy, a facial problem could be mange and near the tail is most likely a problem with fleas. Hair loss on the back half of the body are often due to food allergy or atopy (hypersensitivity to allergens in the air such as pollen, dust mites or mold spores)
Certain breeds have a higher incidence of cat skin problems. For example:
- Abyssinian cats: earwax and cat ear canal infection (otitis externa), excessive grooming (feline psychogenic alopecia)
- Persian cats: cat walking dandruff (caused by mites, cheyletieliosis, cheyletiella dermatitis), Ringworm (dermatophytosis), superficial dermatitis that occurs in skin folds due to moisture that leads to skin infection, feline seborrhea (skin flaking)
- Siamese cats: food allergy, hair loss (feline hypotrichosis), white cat hair around eyes (periocular leukotrichia), cat white skin patches (cat vitiligo)
There are also problems that are unique to kitten skin.
Treatment of Cat Skin Problems
The treatment of the diseases and conditions associated with feline skin problems depends on the exact disease or condition.
Home Cat Skin Treatment and Remedies
If the cat skin condition is mild, meaning there is mild skin itch or skin flaking, then you can try home treatment. First, look for an early stage cat flea problem. Even if you don't see fleas in your home or on your cat, don't immediately eliminate this as a possible cause since fleas are great at hiding. Also, contrary to popular belief, fleas are one of those cat skin problems that can occur at any time of the year. To check for cat fleas, use a flea comb and comb through your cat's coat, with special focus on the area just above the tail and also be sure to carefully examine the back part of the thighs.If you suspect cat fleas, you'll want to kill the fleas that are on your cat using a product such as Adams Plus, followed by the use of a flea preventative. If this is the cause be sure to also clean your cat's environment to remove any hiding fleas. Check with your Vet for a specific product recommendation as well.
Cat Shampoo Therapy for Cat Skin Problems
Next, if you rule out fleas as the cause of the cat skin problems, you can try bathing your cat in a colloidal oatmeal shampoo such as Avoderm or use over-the-counter sprays or waterless bath foam (if your cat hates baths) to see if you can bring some relief. These are not cures, but can help with symptoms. Avoid using medicated shampoos at first, as these can often irritate the skin. If the natural shampoos don't help, then a medicated cat shampoo is worth a try (see below). The key to shampoo therapy is contact with the skin, which isn't always easy with a cat that hates the water.
Instructions for Applying Cat Shampoo
The ideal length of time for a shampoo to stay in contact with the skin is 10 minutes. If you cat allows it, massage into the skin, and then rinse the shampoo off your cat for 5 to 10 minutes.
If the non-medicated approach does not help, try these shampoos depending on the symptoms and suspected cause of the condition.

If you notice the cat skin condition worsening, despite your home treatment, see a Vet. Always see a Vet if you see hair loss, red skin areas, pus or oozing areas on the skin.
Also, if your cat has scratched herself too much, antibiotics may be necessary, as a secondary bacterial infection may have set in. Treatment may involve oral or topical medications.
Treatment may also involve surgical removal of any lumps or bumps from your cat’s skin. This is usually only done if the growth is cancerous or if it seems to be bothering your pet. If it is benign and is not causing your cat discomfort, it can be left alone.
There are several over the counter homeopathic products that could help to improve overall skin and coat condition such as Skin and Coat Tonic. Other over the counter products such as Dermasol contain Vitamin A, which can help to promote the healing of skin.
