Despite its misleading name, ringworm is caused by a fungal infection, not a worm. The fungus that causes ringworm, dermatophytes, can infect humans and animals. It is spread through direct contact of either an infected animal or its infected environment. Cats are common carriers of ringworm. Here are common symptoms to watch for.
-
"Cigarette Ash" Rash
-
Cats can develop small rash regions that look like cigarette ashes, or bad burns. The main sites for the lesions are on the head, chest, forelegs and along the base of the tail.
Hair Loss
-
Ringworm in cats can manifest as hair loss. The hair loss will frequently occur in patches and may be accompanied by the "cigarette ash" rashes.
Scaly or Deformed Claws
-
If ringworm infects the claws, they can become rough and develop a scaly base. If left untreated, the claws could become permanently deformed.
Scratching
-
While most cats may not experience itching, ringworm infections can itch. You may notice a cat scratching often in the area of the infection.
Fluorescence
-
The majority of feline ringworm cases will show as a yellow-green fluorescence under a special UV light. Your vet can perform this test. Not all species of ringworm will glow, but the most common ones do.
