Dear Obie,
I recently returned from volunteering with the cats at Best Friends in Kanab, Utah, and one of the cats there has ringworm. What is ringworm?

Dear Fred,
In spite of its name, ringworm has nothing to do with worms. Ringworm is a fungal infection that affects the hair, skin and nails of dogs and cats, and also humans! Though ringworm will self cure with time, all pet owners need to be aware of what ringworm is, how to identify it, and treatment options.

There are several different fungi that cause ringworm, and are normally found on an infected animal or in an area where an infected animal has been. Spores shed into the environment can live for up to 24 months, and can exist on bedding, carpeting, drapes, and combs and brushes.

Some animals will carry the organism without ever showing signs or symptoms. Humid environments are the most conducive to the organism, but it exists in all climates.

Most healthy cats have a natural immunity to ringworm, though any cat can be infected with exposure. Kittens under one year of age and cats with other underlying illnesses or reduced immunity are more likely to be infected.

Ringworm normally appears as small round lesions on the ears, head or tail. These round shapes are what originally gave the organism the name of ringworm. The lesions are usually scaly and hairless. On occasion, a cat's entire body can be affected, resulting in excessive hair loss and itching.

It is important to always exercise caution when introducing a new pet into a household with existing pets. Any new pet should be seen by a vet prior to being mixed with your existing cats or dogs. At the first sign of possible ringworm, isolate the pet from your other animals and get to your vet as soon as possible.

Your vet will run some very simple tests and will most likely prescribe an antifungal ointment with thiabendazole or miconazole. There are also shampoos available that contain miconazole, and advanced cases may require oral medications or even lime sulfur dips! Long-haired cats may need to be shaved in order for the medication to reach the affected skin areas.

It is important to help your pet fight the organism by providing good nutrition and by strictly following any directions given to you by your vet!

Because the spores can live so long in the environment, cleaning an affected area is vitally important. Carpet should be steam-cleaned. Vacuum rugs and drapes and immediately dispose of the vacuum bags. Mop floors instead of sweeping, because sweeping just sends the spores floating happily across your house. Wash all bedding and clothing in a bleach mixture.

As I always say, your vet is your best friend in fighting any health issues with your pet. Listen to what they say! They're pretty smart people!

Thanks for the email!
Your friend, Obie

"I put down my book, 'The Meaning of Zen,' and look at my cat smiling into her fur as she delicately combs it with her rough pink tongue. 'Cat, I would lend you this book to study, but it appears you have already read it.' She looks up and gives me her full gaze. 'Don't be ridiculous,' she purrs. 'I wrote it.'"

I hope you are all doing well! I miss getting emails! Please email your cat questions to me, or questions about any animal-related topic!
