Skin Disease in Cats: Our Vet Explains Causes, Signs & Treatments

Share

Skin disease in cats is incredibly common. Cat’s skin plays an important role, and it is the largest organ in your cat’s body. It functions as a protective barrier to the outside world and helps your cat regulate their body temperature.

There are many different conditions that can cause skin disease in cats. There are contributing factors in your cat’s environment, as well as your cat’s genetics and lifestyle. Skin disease can be very complicated and treatment options vary depending on the underlying cause. It is important to take your cat to see a vet immediately if you notice any problems with their skin as prompt diagnosis and treatment will mean a better prognosis.

What Is Skin Disease in Cats?

Skin disease in cats can be a serious and debilitating condition. It is caused by a number of different conditions, some directly affecting the skin, others causing disease elsewhere in the body that has an effect on the skin later on in the disease process. Causes can include injuries, wounds, parasites, infections, and allergies.

A cat’s gender, breed, and general habits can have a profound effect on the condition of their skin. Cats that go outdoors are at higher risk of picking up parasites and getting injuries climbing and jumping. They are also more likely to encounter other cats and potentially get into cat fights and get wounds and abscesses. Male cats that have not been neutered are more likely to become aggressive and territorial which can result in more fights with other cats.

Skin disease is a broad category that describes any disorder of the skin. Common signs of skin problems in cats include redness, itching, licking, lumps, bumps and rashes, alopecia and scabs, ulcers, and swelling.

The skin has three main layers.

These consist of:
  • The outer layer, or epidermis. This is the protective layer.
  • The middle layer, or dermis. This is a supportive layer that provides nourishment to the outer layer.
  • The inner layer, or subcutis, contains muscle and fat that protects and insulates the cat.

There are other important components such as the hair and claws, also known as the skin appendages, and the subcutaneous fat and muscles. There are small muscles in the skin called arrector pili that are responsible for making the cat’s hair stand on end. Skin also contains sebaceous glands that produce lubrication for the hair and skin.

Skin disease can affect all of the layers of the skin and the appendages. Some skin disorders start at the epidermis and some start in the deeper layers.

What Are the Signs of Skin Disease in Cats?

Due to the many different causes of skin disorders, there can be lots of clinical signs. Some of the clinical signs owners report initially are ways in which the cat is responding to the disease, trying to alleviate itchiness or reacting to pain, so can seem generalized and relatively non-specific. Some cats are very good at hiding or masking clinical signs so may not show any behavioral changes in front of their owners.

The clinical signs reported vary depending on the underlying cause of the condition.

Common signs of skin disease seen in cats include:
  • Excessive scratching of skin
  • Licking of fur
  • Chewing paws
  • Rubbing themselves on objects
  • Redness
  • Hair loss (alopecia)
  • Scabs
  • Scaling/flaking skin
  • Lumps or bumps on the skin surface
  • Broken skin
  • Weeping wounds
  • Ulcerative lesions
  • Dryness
  • Visible parasites
  • Matted hair
  • Rash

What Are the Causes of Skin Disease in Cats?

There are many causes of skin disease in cats. The most commonly encountered are listed below:

Parasites

Both indoor and outdoor cats can pick up parasites. Outdoor cats are more prone to picking them up as they are exposed to more in their environment. Fleas cause itchiness and can cause cats to over groom and cause damage. Some cats are also allergic to the saliva of fleas and they have a serious reaction when they are bitten.

Lice and mites can also affect cats. Ear mites are common in kittens. Ticks are small blood-sucking parasites that latch onto cats’ skin and can spread tick-borne diseases as well.

Infections

Skin infections are a very common cause of skin disease in cats. Infections can be bacterial, viral, fungal, or yeast in origin.

Allergies

Skin allergies occur when a cat is exposed to something in their immediate environment that causes their immune system to overreact. This can be environmental such as pollen, dust, or mold. Some cats can have food allergies that cause skin lesions. Some cats are allergic to fleas or other parasites.

Cancer

Cats can get different types of skin cancer. These skin cancers can take on different forms. Common types of skin cancer seen in cats include malignant melanoma, squamous cell carcinoma, and mast cell tumors. Cats can also get benign tumors and lumps such as cysts.

Nutritional Disorders

Nutritional disorders can affect cats’ skin. One of the main ways is a nutritional deficiency if a cat is being fed a lower quality diet that is missing viral components, or if they are using inappropriate supplements.

Endocrine Disease

Some endocrine disorders affect cats’ skin. Common diseases such as hypothyroidism and hyperadrenocorticism cause dramatic changes in the skin such as hair loss, thinning of the skin, changes in pigmentation, and dryness and scaling.

Self Trauma

Some cats overgroom themselves because they are stressed or anxious. They may be suffering from separation anxiety or are bored and lacking mental stimulation.

Wounds and Injuries

Wounds and injuries such as cuts and scrapes or cat bite abscesses from fights can be very painful and become infected.

Diagnosis of Skin Disease in Cats

Skin disease can be very complicated and determining the underlying cause is often the most challenging part for vets. A vet will take a full clinical history and examine your cat. They will perform a full analysis of your cat’s skin. This will involve taking samples if necessary, such as tape strip impressions, hair plucks, skin scrapes, swabs for culture and sensitivity, and fine needle or excisional biopsies. They may examine your cat under a special lamp called a “Woods Lamp” to check for fungal infections.

The vet may also take routine blood tests and urinalysis to assess the general health of your cat. There are other more specific blood tests the vet may take as well if they have suspicions about a certain skin disease.

Treatment of skin disease requires prompt identification of the underlying cause. Many effective skin treatments are applied directly to the skin as topical medications.

Other things a vet may prescribe include:
  • Oral antibiotics for bacterial infections
  • Corticosteroids to combat inflammation
  • Anti-parasite medication for ectoparasites
  • Anti-fungal medication for ringworm or other fungal diseases
  • Medicated shampoo for yeast infections
  • Chemotherapy drugs for skin tumors
  • Behavioral therapy for behavior problems such as separation anxiety
  • Specific medication for endocrine diseases
  • Diet changes/food exclusion diet for food allergies or nutritional deficiencies
  • Immunotherapy for allergies
  • Non-steroidal anti-inflammatory drugs for pain relief and anti-inflammatory action
