What Is Ringworm in Cats?

Despite the name, ringworm isn’t caused by worms. It’s a fungal infection caused by dermatophytes, which feed on keratin found in your cat’s skin, fur, and nails. The fungus thrives in warm, humid environments, making it a year-round risk—especially in multi-pet households or shelters.

Key Facts:

  • Ringworm is a zoonotic infection, meaning it can spread from animals to humans.
  • It’s highly contagious among pets.
  • Early diagnosis = faster recovery + reduced spread.
