Feline Ringworm is one of the most common skin disorders affecting cats worldwide. Despite the name of this disorder, it is a topical fungal skin infection that has no connection to or involvement with “worms” of any kind. However, the condition often (but not always) generates circular patches of red and/or crusty skin that may have a red raised area on the edges of the circular area that resembles a ring. As the disease progresses, some or all of the cats’s fur will break off or fall out of the circular patches leaving bald or stubby patches that may also have inflamed, thick scaling crusty skin. In other areas, such as the ears, the whole ear is often infected and most of the hair will fall out and not show any ring like pattern. Ringworm can infect the cat’s claws and nail beds as well as their fur. Ringworm is fully treatable and curable but it can take 6 weeks (and occasionally longer) to fully resolve, while maintaining treatment with medications. Depending on the severity of the infection, topical medications, oral medication, shampoo and dips may be prescribed by your veterinarian.The fungi responsible for Feline Ringworm originate in the soil and can infect both people and animals that come in contact with it. It is highly contagious from cat to cat as the fungal infection generates microscopic spores that are capable of spreading the disease. Cats (and children) can get ringworm from the soil outside and cats/kittens are often infected by other cats in outdoor cat colonies and from their mother cat. It can be spread by coming in direct contact with an infected animal or person, or by handling contaminated objects or surfaces. However, a high enough concentration of spores is required to spread the fungal infection. These spores can spread in an indoor environment as well and may remain dormant on combs, brushes, food bowls, furniture, bedding, carpet or other surfaces for as many as 18 months. However, diluted bleach, apple cider vinegar and other commercially available products can kill ringworm spores, and hot water and detergent can be used on bedding and clothes in a washing machine.Ringworm is the same variety of fungal infection that causes athlete's foot or jock itch in people. However, human skin responds to treatment faster than animal hide (about 2 weeks instead of 6 weeks) and is easily treatable/curable by over-the-counter medications in most cases.
