Symptoms of Ringworm
Some cats display no symptoms at all, while others will have flaky round patches that may resemble dandruff or small lesions on the skin. Your vet can diagnose ringworm by looking at the patches under ultraviolet light or taking a sample to be analyzed.
Treatment for Ringworm
Shampoo or ointment are both very effective at treating ringworm in cats. In some severe cases, oral medication may also be necessary. The treatment may last several months to ensure the ringworm is completely eradicated. Be warned that any cats you bring into your home after a ringworm infection will probably also contract the fungus.
If left untreated, your cat can develop ringworm on his entire body, which contributes to skin infections and general discomfort. Additionally, the humans and other pets in your household will likely contract the disease unless aggressive efforts are made to treat and eradicate it.
The best way to prevent ringworm is to be careful when bringing new cats home, and to wash your hands thoroughly when you touch a strange cat. Disinfecting anything that has come in contact with an infected cat will help remove it from the environment, but the best treatment is to take steps to prevent it in the first place.
