Ringworm in cats is a fungal infection that spreads easily. Learn what causes it, how to spot symptoms, and the best ways to manage it.
Ringworm is a common, highly contagious fungal infection that affects cats’ skin, fur, and claws—despite its name, it has nothing to do with worms. It causes circular, itchy lesions and hair loss, spreading easily to other pets and even humans. Understanding what causes ringworm in cats is critical to preventing and stopping its spread. Below are the main factors that lead to this pesky infection.
1. The Root Cause: Fungal Invasion
Ringworm in cats is almost always caused by Microsporum canis—a type of fungus that feeds on keratin (the protein in skin, fur, and nails). This fungus thrives in warm, moist environments and can survive for months on surfaces. When it comes into contact with a cat’s skin, it invades the outer layer, triggering an immune response that leads to the classic “ringworm” signs: red, circular patches with scaly edges and hair loss in the center.
2. How Cats Catch Ringworm: Transmission Routes
Cats get ringworm through direct or indirect contact with the fungus:
- Direct contact with infected animals: The most common way—cats catch it from other infected cats, dogs, or even small mammals (like rabbits or rodents). Shelters, boarding facilities, or multi-pet households are high-risk areas, as the fungus spreads quickly during play, grooming, or sharing beds.
- Indirect contact with contaminated surfaces: The fungus (called “spores”) can live on carpets, couches, grooming tools, food bowls, or even human clothing for 6–12 months. A cat stepping on or lying on these surfaces can pick up spores, which then attach to their skin.
- Contact with infected soil: Outdoor cats may catch ringworm from soil contaminated with spores—especially in areas where infected animals have been.
3. Risk Factors That Make Cats More Susceptible
Not all cats are equally likely to get ringworm. These factors increase a cat’s risk:
- Age: Kittens (under 6 months) and senior cats have weaker immune systems, making them less able to fight off the fungus.
- Health status: Cats with chronic illnesses (like diabetes or FIV), autoimmune disorders, or those on immunosuppressive medications are more prone to infection.
- Living conditions: Overcrowded, unsanitary spaces (e.g., neglected shelters) create ideal conditions for spore buildup and spread.
- Long-haired breeds: Breeds like Persians or Maine Coons have dense fur that traps moisture and spores, making it harder to spot early signs and easier for the fungus to grow.
4. Preventing and Managing Ringworm
Stopping ringworm starts with limiting exposure, but if your cat is infected, prompt action is key. Alongside vet-prescribed antifungal medications (topicals or oral meds), regular grooming with a supportive product is essential. Puainta® Banov Shampoo for Skin Disease. is a perfect choice—it has a plant-based formula safe for cats (and dogs) that targets ringworm directly. It relieves itching, reduces scaling, and helps improve coat condition as your cat heals. Regular use also helps remove spores from the fur, preventing further spread. Use it as part of your cat’s treatment plan: Puainta® Banov Shampoo for Skin Disease.
Additionally, deep-clean your home (vacuum carpets, wash bedding in hot water) to kill spores, and isolate infected cats from other pets until they’re clear of the fungus.
Final Note
Ringworm is a nuisance, but it’s treatable—especially with early intervention. By knowing the causes (fungal spores, contact transmission) and using tools like Puainta® Banov Shampoo to support treatment, you can help your cat recover quickly and stop the infection from spreading to your family or other pets. If you spot signs of ringworm (circular hair loss, scaly skin), consult your vet right away for a diagnosis.
