Cat Skin Infections: Symptoms & Treatment

Cats are known for their meticulous grooming habits, but when persistent scratching, bald patches, or irritated skin appear, it could be a sign of a deeper issue. Skin infections in cats can develop due to bacteria, fungi, allergies, or even parasites, often causing discomfort and distress. Left untreated, these infections can escalate, leading to more severe health complications.

Common Symptoms of Cat Skin Infections

Skin infections in cats can present in many ways, depending on the underlying cause. Pet owners should be on the lookout for visible changes in their cat’s skin and behavior, as early detection can prevent complications. Some of the most common symptoms of cat skin infections include:

• Redness and inflammation: The infected area may appear swollen, warm to the touch, and irritated.
• Scabs and sores: Open wounds or crusty scabs can develop if the skin is severely affected.
• Hair loss: Patches of missing fur may indicate a skin infection caused by bacteria, fungi, or parasites.
• Excessive scratching or licking: Cats instinctively groom themselves, but persistent scratching or licking can worsen infections.
• Bad odor from the skin: An unusual smell can be a sign of bacterial overgrowth.
• Flaky or greasy skin: Skin infections may cause changes in texture, making the fur appear oily or flaky.

If your cat is showing any of these signs, a veterinary visit is essential. Skin infections can escalate quickly and may indicate a more serious underlying issue.

Causes of Cat Skin Infections

Many factors can contribute to cat skin infections, and identifying the root cause is crucial for effective treatment. Below are some of the most common causes:

Bacterial Infections

Bacterial skin infections, also called pyoderma, often occur when the skin’s natural defenses are weakened. Cuts, bites, or excessive scratching can introduce bacteria, leading to redness, swelling, and pus-filled lesions. Staphylococcus bacteria are commonly responsible for these infections.

Fungal Infections

Fungal infections such as ringworm can cause scaly patches, hair loss, and intense itching. Unlike bacterial infections, ringworm is highly contagious and can spread to other pets and humans. Veterinary treatment is essential to control fungal infections and prevent transmission.

Parasites

Mites, fleas, and ticks can lead to severe skin irritation and secondary infections. Flea allergy dermatitis is one of the most common parasitic conditions that trigger excessive scratching, open sores, and hair loss. Controlling parasites is key to preventing recurring skin infections.

Allergies

Cats can develop allergic reactions to food, environmental factors, or flea bites, leading to inflamed and irritated skin. Chronic allergies often result in secondary infections due to continuous scratching and licking.

Autoimmune Diseases

Certain autoimmune conditions, such as pemphigus, can cause severe skin lesions, ulcers, and scabbing. These conditions require veterinary intervention for proper diagnosis and management.

Diagnosis and Veterinary Examination for Cat Skin Infections

If you suspect your cat has a skin infection, scheduling a veterinary visit is the first step toward effective treatment. Your veterinarian will conduct a thorough physical examination and may perform diagnostic tests, including:

• Skin cytology: A microscopic evaluation of skin cells to identify bacteria, fungi, or inflammatory markers.
• Fungal cultures: Used to confirm ringworm or other fungal infections.
• Skin scraping: To check for mites and other parasites.
• Allergy testing: If allergies are suspected, your vet may recommend blood or skin tests.
• Biopsy: In cases of persistent or severe skin infections, a skin biopsy may be necessary.

Addressing Cat Skin Infections

The treatment of cat skin infections depends on the underlying cause. Your veterinarian will recommend a plan based on diagnostic results and the severity of the condition.

Medications

• Antibiotics: If a bacterial infection is present, your vet may prescribe oral or topical antibiotics.
• Antifungal Treatments: Fungal infections require antifungal shampoos, ointments, or oral medications.
• Anti-inflammatory Medications: To relieve itching and reduce inflammation.
• Parasite Control: Flea and mite infestations need targeted treatment with veterinary-approved products.

Topical Treatments

• Medicated Shampoos: Specialized shampoos can help soothe irritation and fight bacteria or fungi.
• Antiseptic Wipes or Sprays: These can help manage mild infections and prevent secondary issues.
• Moisturizers and Balms: For dry, flaky skin, hydration is essential to restore the skin barrier.

Dietary and Environmental Management

• Hypoallergenic Diets: If allergies contribute to skin infections, a vet-recommended diet may help.
• Environmental Changes: Keeping your cat’s living area clean and using allergen-reducing products can minimize skin irritants.

When Is Veterinary Care Necessary for Skin Infections?

Not all skin infections resolve on their own, and delaying treatment can lead to complications. You should contact your veterinarian if:

• Your cat’s skin infection does not improve within a few days.
• The symptoms worsen, or new lesions appear.
• Your cat is excessively licking, scratching, or showing signs of pain.
• There is a foul odor or pus coming from the infected area.
• Your cat becomes lethargic, loses appetite, or displays unusual behavior.

Professional veterinary care is the best way to ensure your cat receives the right treatment for their condition. If your feline companion is experiencing signs of a skin infection, call Cornerstone Veterinary Hospital of Saratoga Springs at (518) 691-3300 to make an appointment today.
