🐾 Vet’s Guide to Feline Pyoderma: Symptoms, Treatment & Prevention in 2025 🐾

By Dr Duncan Houston BVSc

Pyoderma is a bacterial skin infection in cats that can cause discomfort and lead to more serious health issues if left untreated. This guide provides comprehensive information on the symptoms, treatment, and prevention of feline pyoderma, tailored for Australian cat owners in 2025.

🔬 What is Pyoderma?

Pyoderma, meaning "pus in the skin," refers to bacterial infections that result in the formation of pus-filled lesions. In cats, pyoderma is less common than in dogs but can still pose significant health concerns. The condition can be classified based on the depth of the infection:

• 🐾 Surface Pyoderma: Affects only the surface layer of the skin.
• 🐾 Superficial Pyoderma: Involves the epidermis and hair follicles.
• 🐾 Deep Pyoderma: Extends into the dermis and subcutaneous tissues.

Common bacterial culprits include Staphylococcus pseudintermedius and Pasteurella multocida, which are part of the normal flora but can cause infections when the skin's protective barrier is compromised. ^PetMD

🦠 Causes and Risk Factors

Several factors can predispose cats to pyoderma:

• 🐾 Allergies: Environmental, food, or flea allergies can lead to skin irritation and secondary infections.
• 🐾 Parasites: Fleas, mites, and other parasites can damage the skin, allowing bacteria to enter.
• 🐾 Hormonal Disorders: Conditions like hyperthyroidism can affect skin health.
• 🐾 Immune Suppression: Diseases like FIV or FeLV can weaken the immune system.
• 🐾 Poor Grooming: Especially in obese or elderly cats, can lead to skin infections.
• 🐾 Skin Trauma: Wounds, scratches, or bites can introduce bacteria into the skin.

🐱 Symptoms of Pyoderma

Signs of pyoderma in cats can vary but often include:

• 🐾 Redness and inflammation of the skin
• 🐾 Pustules or pimples
• 🐾 Crusts and scabs
• 🐾 Hair loss in affected areas
• 🐾 Itching and scratching
• 🐾 Foul odor from the skin
• 🐾 Pain or discomfort when touched

These symptoms are often found on the face, neck, and trunk but can appear anywhere on the body. ^PetMD

🩺 Diagnosis

Diagnosing pyoderma involves a thorough veterinary examination, including:

• 🐾 Skin Cytology: Examining skin samples under a microscope to identify bacteria.
• 🐾 Skin Scraping: To rule out parasites like mites.
• 🐾 Fungal Culture: To exclude fungal infections like ringworm.
• 🐾 Bacterial Culture and Sensitivity: To identify the specific bacteria and determine the most effective antibiotic treatment.

💊 Treatment Options

Treatment depends on the severity and depth of the infection:

• 🐾 Topical Therapies: Antibacterial shampoos, creams, or ointments for mild cases.
• 🐾 Systemic Antibiotics: Oral or injectable antibiotics for more severe or widespread infections.
• 🐾 Addressing Underlying Causes: Managing allergies, parasites, or hormonal imbalances to prevent recurrence.

It's crucial to complete the full course of antibiotics as prescribed, even if symptoms improve before the medication is finished. ^PetMD

🛡️ Prevention Strategies

Preventing pyoderma involves maintaining overall skin health and addressing potential risk factors:

• 🐾 Regular grooming to keep the skin and coat clean.
• 🐾 Prompt treatment of wounds or skin injuries.
• 🐾 Effective flea and parasite control.
• 🐾 Managing underlying health conditions with veterinary guidance.
• 🐾 Providing a balanced diet to support immune function.

📍 Regional Considerations in Australia

In Australia, the warm and humid climate can predispose cats to skin infections. Additionally, outdoor cats are at higher risk due to increased exposure to parasites and environmental hazards. Regular veterinary check-ups and preventive care are essential for early detection and management of skin conditions.
