Ringworm is a typical skin disease that affects many cats. This medical condition is actually not caused by worms at all, but rather by a fungus. The sores on the skin due to ringworm fungi are circular, which led to the belief at once time that a curling worm under the skin caused this disease.
Cats and humans may not look much alike, but remember, both are mammals. Therefore, there are a number of diseases, disorders, and other medical conditions found in humans that are also found in cats. One such disease is diabetes.
