When you first bring home a new kitten, you find yourself going to the vet every couple of weeks for different vaccinations. In addition to having your kitten vaccinated, you’re probably going to need to have him de-wormed – especially if you adopted him from a shelter. Worms are one of the least pleasant things you’ll find yourself facing as a cat owner, but they may be less common than you might imagine. What’s more common is a condition that has “worm” in the name but nothing to do with actual worms – ringworm.

Ringworm is a common skin condition in cats and, though serious, it is entirely treatable. In this article, we’ll explore the subject of ringworm in cats to learn where it comes from, what kills ringworm in cats, and how medicated shampoo should be part of your cat’s treatment plan.

Though the name might bring to mind pictures of slimy legless creatures, ringworm doesn’t actually have anything to do with worms. It’s a common fungal infection that forms in the superficial layers of skin. The name comes from the ring-like appearance of rash characteristic to the disease.

The organisms responsible for ringworm are a specialized group of fungi called dermatophytes. This is why ringworm in cats is also known as feline dermatophytosis. Some dermatophytes are species-specific, though many are infectious to cats as well as dogs and humans. Microsporum canis, the species responsible for almost all ringworm infections, is also infectious to humans.

Because your cat’s body is covered in a layer of fur, it can be difficult to detect skin conditions like ringworm. The fungi responsible for ringworm feed on the keratin found in the outer layers of the skin, hair, and nails. Ash-like scaling is often the only visible indicator of ringworm infection in cats, though some develop thickened patches of skin paired with hair loss. These lesions typically form on the chest, head, legs, or back and they don’t tend to itch.

Tips for Treating Ringworm in Cats

Ringworm is very contagious and can be transmitted through direct contact with the fungus. This means your cat can get it through contact with an infected animal or person or through touching a contaminated surface. Ringworm spores can live on surfaces like cat brushes, food bowls, and furniture for as long as 18 months.

After exposure to ringworm fungus, the disease incubates for 7 to 14 days before lesions appear. Diagnosis of ringworm in cats may involve the use of a special UV lamp called a Wood’s lamp or through a fungal culture taken from hair and skin scrapings. Without treatment, ringworm may resolve in 3 to 5 months, but treatment is recommended to limit the spread.

Here are some tips for treating ringworm in cats:

  • Apply medicated ointment or cream to the skin affected by the ringworm – you may need to trim or shave the hair in this area to reach the skin.
  • Bathe the cat twice weekly with a medicated shampoo for ringworm – this is particularly recommended for longhair cats because treatment with topical applications can be tricky.
  • Consider administering an oral anti-fungal drug like griseofulvin for at least 6 weeks – it’s important to complete the course of treatment or the infection may recur.
  • Thoroughly clean your household including pet toys, brushes, and bedding to eliminate fungal spores – you can use a diluted bleach solution.
Now that you have a better understanding of what ringworm is and how to treat it, you’re ready to talk to your veterinarian. Your vet will help you determine the best course of cat ringworm treatment which may include medicated shampoo. Read on to see our top picks.

Frequently Asked Questions

  1. How do cats get ringworm? Ringworm is a fungal infection spread through direct contact with an infected host or contaminated surfaces. Your cat could contract ringworm through direct contact with another infected cat or from another animal. He could come into contact with the fungal spores by touching a contaminated surface like a cat bed, food bowl, or shared pet brush.
  2. How do you know if your cat has ringworm? In many cases, ringworm is mild and difficult to detect but there are some signs to look for. The most obvious sign is the classic ring-like lesion that forms on the skin. These lesions usually appear on the legs, ears, and head but can be found anywhere on the body in severe infections. The lesion may begin with a patch of hair loss that progresses to redness and inflammation – some cats find the lesions very itchy. In more mild cases of ringworm, you may only notice an ash-like dusting in your cat’s coat – like dandruff.
  3. Can you get ringworm from a cat? Once your cat is infected with ringworm, he will remain contagious for about 3 weeks with aggressive treatment. Without treatment, your cat could spread the disease for much longer. Whether the condition can be spread to humans depends on the microorganisms themselves, but the most common type of ringworm is caused by Microsporum canis which can be spread to dogs and people.
  4. What kills ringworm in cats? The most effective cat ringworm treatment is an oral anti-fungal mediation. Topical ointments and creams can help soothe inflammation and heal the skin, as can bathing with ringworm shampoo for cats. The key to killing ringworm is to complete the entire course of treatment – this condition is very contagious and will come back if you don’t treat it aggressively. When it comes to a ringworm home remedy, you won’t find one as effective as oral anti-fungals. If you want to avoid traditional treatments, the infection will usually resolve itself within a few months.

Though ringworm is highly contagious, it is also both treatable and preventable. Keeping your cat indoors and maintaining a sanitary living environment are two key steps in keeping your cat protected. If you do notice signs of ringworm, talk to your veterinarian immediately to start a course of treatment. In the meantime, consider some of the medicated ringworm shampoo for cat options reviewed above.
