Ringworm is a fungus that infects cats, dogs and humans. It is the most common contagious skin infection in cats. In some cases, cats develop severe skin problems and hair loss due to infection, but they can also be carriers and shed the spores without experiencing symptoms.

Signs of Infection
-
Ringworm in cats typically results in small, sometimes itchy lesions devoid of hair, which may contain pustules and crusty, scaly skin. They are most commonly found on the head, ears and tail, but in severe cases can cover the entire body.
Transmission
-
Ringworm is transmitted by fungal spores that can be found on an infected cat, on brushes used on the infected cat and all over the environment where the cat has been. Spores survive in carpets and furniture for long periods of time and may be difficult to eliminate.
Risk
-
Healthy adult cats usually have a natural resistance to ringworm. Kittens, senior cats and cats that are malnourished, sick or under stress are at increased risk, and Persian and Himalayan cats are particularly susceptible.
Diagnosis
-
To diagnose ringworm, a veterinarian performs a fungal culture using a sample of a cat's skin and hair. Some species of ringworm glow under black light and can be diagnosed this way.
Treatment
-
Small lesions can be treated with a topical antifungal cream, but in more severe cases, a combination of lime sulfur dips and an oral antifungal agent is recommended. Long-haired cats must be shaved for these dips to be effective.
