Scabs in Cats Back

Scabs in Cats: Causes, Diagnosis and Treatment Methods

The appearance of single or multiple scabs in cats is a fairly common occurrence. Cat owners often notice such problems and do not quite understand what to do. These symptoms may indicate either a normal reaction to flea bites, minor irritation, or serious dermatological or internal diseases. Therefore, it is important to closely monitor the animal’s condition and consult a veterinarian if necessary. In this article, we will take a detailed look at why such scabs may appear and what the main factors are that cause them. Learn how to identify and treat common cat skin problems.

The Main Causes of Scabs on a Cats Back

1. Flea allergy dermatitis

The most common factor is miliary dermatitis, which develops as a result of an allergic reaction to flea saliva. This condition is observed in approximately 80% of cats with dermatitis. Even a single bite is enough for symptoms to appear. Affected skin usually itches, becomes inflamed, and the cat may constantly scratch or lick the affected area. If left untreated, itching and irritation can lead to secondary bacterial infections.

2. Other types of allergic reactions can also cause scabs:

• Food allergies, which occur due to intolerance to individual food components.
• Inhalant allergies, which occur when there is an increased sensitivity to pollen, dust, smoke or mold.
• Contact allergies, which occur after the skin comes into contact with household products, bedding or animal collars.

3. Skin infections

Most skin infections are secondary in nature and develop against the background of other diseases, such as hypothyroidism or Cushing’s disease. They can cause inflammation, itching, and scabbing.

4. Mite infestations

These include:

• Cheyletiellosis;
• Notoedric mange;
• Demodicosis.

All of these parasites cause irritation, itching, and inflammatory reactions on the skin.

5. Ringworm

This is a fungal infection that most often affects cats in shelters, nurseries, or animals with weakened immune systems. The affected areas of the skin become covered with scabs and the hair falls out.

6. Abscess

An abscess is a purulent inflammation that usually occurs after being bitten by another cat. When the abscess bursts, a scab appears in its place.

Due to the variety of causes of scabs in cats, it is worth consulting a veterinarian first, as the owner cannot always correctly determine the cause of the disease, let alone prescribe the correct treatment.

The Main Symptoms of Diseases that Cause Scabs in Cats

1. Miliary dermatitis

This condition is characterized by small, dry, dense scabs, similar to millet grains, mainly on the back, near the tail, and around the neck. The skin becomes dry, rough, and may twitch noticeably when touched. Because it is easier for cats to scratch their necks, scratches and open wounds often appear in this area. Associated symptoms: severe itching and hair loss.

2. Ringworm

This is a fungal infection that manifests itself as round, scaly, red spots that gradually increase in size. Pustules (pimples) and itching are possible. Lesions most often appear on the head and ears, but can affect any part of the body.

3. Mite infestation

Characteristic signs: hair loss or thinning, crusting, intense itching. Secondary bacterial infections often develop, which exacerbate skin irritation and inflammation. In some cases, the skin becomes reddened, thickened, or small ulcers appear. Without timely treatment, mites can quickly spread throughout the body and infect other animals in the home.

4. Abscess

An abscess appears as a localized, firm, and painful swelling. Additional symptoms: fever, lethargy, loss of appetite. As the abscess matures, the skin above it thins, and eventually it ruptures, releasing pus with an unpleasant odor.

5. Skin infections

Crusts and flakes are observed. Hair in these areas is usually easy to pull out. Hair loss, itching (constant or periodic), and unpleasant skin odor may occur. The affected areas often become red and painful. If left untreated, the infection can spread deeper into the skin and cause systemic inflammation.

Diagnosing the Causes of Scabs

1. Interview and initial examination

During the appointment, the veterinarian will conduct a complete physical examination of the animal and collect its medical history. To determine the possible causes, they may ask the following questions:

• How long ago did the symptoms appear?
• Is the cat treated regularly for fleas?
• What flea treatment is used?
• Does the cat have access to the outdoors?
• Do the symptoms disappear and reappear?
• Have you noticed any other changes in the animal’s behavior or condition?
• What is the cat’s diet?
• Is it taking any medication?

2. Initial diagnosis

Miliary dermatitis can usually be recognized by its characteristic external manifestations. However, to clarify the causes, the veterinarian may order additional laboratory tests.

3. Possible additional tests

• Analysis of combed hair and fur samples

Performed to detect parasites (mites, fleas) or fungal infections.

• Skin prick test (allergy test)

A patch of skin is shaved and several allergens are applied to determine the body’s reaction and identify the exact allergen.

• Dermatophyte culture (DTM)

Hair or dandruff samples are taken from the affected area and placed in a special medium to test for fungal or yeast infections.

• IgE test

A blood test that detects IgE antibodies characteristic of allergic reactions.

• Skin scrapings

Several layers of skin are taken for examination under a microscope. This allows mites, bacteria, and fungi to be detected.

• Trial elimination diet

If a food allergy is suspected, the cat is switched to a hypoallergenic diet for 6–8 weeks. If the symptoms disappear and return after returning to the old diet, the allergy is confirmed.

Methods of Treating Various Causes of Scabs

1. Miliary dermatitis

Since miliary dermatitis is often associated with flea bites, veterinarians usually begin treatment with flea medication. This helps determine whether the symptoms are related to parasites. It is important to remember that not all cats respond to different treatments in the same way.

Treating the environment is equally important: adult fleas live on the animal, but most of their life cycle takes place in the environment (carpets, furniture, bedding). Therefore, both the home and the animal need to be treated.

• Corticosteroids are prescribed to reduce itching.
• If there is a secondary bacterial infection, antibiotics are used.

2. Other allergies

The main task is to identify and eliminate the irritant that causes the allergic reaction (food, contact, or inhalation).

• Antihistamines or corticosteroids are used to reduce itching.
• Antibiotics are prescribed if a secondary infection develops.

3. Mite infestations

Сat skin scabs treatment depends on the type of mite, but usually includes the following measures:

• Weekly bathing in a lime-sulfur or pyrethrin solution for 6-8 weeks. Long-haired cats may need to have their hair trimmed beforehand.
• Oral administration of ivermectin (daily or weekly) for four weeks under veterinary supervision.
• Washing bedding and blankets in hot water and drying them in the sun.
• Simultaneous treatment of all animals in the home to prevent reinfection.

4. Ringworm

• Oral antifungal medications, medicated baths, and shampoos are prescribed. It is important to simultaneously disinfect the environment by treating surfaces with a 1:10 bleach solution to destroy fungal spores.

5. Skin infections

• First, the underlying cause of the infection must be identified and eliminated.
• To combat bacterial inflammation, the veterinarian prescribes antibiotics.

6. Abscess

• If the abscess has not ruptured on its own, surgical opening and cleaning is performed.
• After that, the wound is washed with an antiseptic solution and antibiotics are prescribed to prevent re-infection.

Don’t ignore scabs on cat. Early treatment can prevent serious skin issues.
