Pyoderma is a bacterial skin infection (bacterial dermatitis). Pyodermas in cats are usually caused by Staphylococcus bacteria (Staphylococcal folliculitis). These bacteria usually will not cause disease on normal skin. However, other underlying skin diseases cause changes in the skin surface and make the skin more susceptible to infection. Pyoderma is uncommon in cats.

Causes of Pyoderma

Common underlying causes of pyoderma in cats include allergies (food allergy or atopy), fleas and other parasites, and hormonal imbalances such as diabetes mellitus. Cats can also develop a deep pyoderma of the chin called feline acne. As pyoderma is usually secondary to an underlying condition, it is important to diagnose and treat other health conditions alongside the pyoderma.

Treatment of Pyoderma

Pyodermas in cats are often treated using topical antibacterial shampoos, sprays, or rinses, and only the more severe pyodermas are treated with antibiotics. However, topical therapy in cats is more difficult because they lick and groom themselves. Commonly used antibiotics for cats with bacterial skin infections include injectable cephalosporin, such as cefovecin, or an oral antibiotic such as amoxicillin-clavulanic acid (Clavamox). Deep skin infections require a longer course of antibiotic treatment. It is important to give the full dose of antibiotics for the entire time prescribed, even if your cat's skin looks much better. Stopping the antibiotic before the prescription is finished may lead to further problems, such as antibiotic resistance or the need to restart treatment from the beginning.

It is equally important to keep your cat's recheck appointment. Medications may need to be adjusted depending on your pet's progress. Again, diagnosis and treatment of the primary problem are the key to preventing pyoderma.
