If your cat has patchy hair loss or skin lesions, it’s natural to feel concerned. One common culprit behind these symptoms is ringworm—a highly contagious fungal infection that can spread quickly among pets and even to people. Learning to recognize the signs of ringworm can help you get the right veterinary care and reduce the risk of transmission to other pets or household members.

What Is Ringworm in Cats?
Ringworm in cats is caused by a group of fungi known as dermatophytes. These fungi feed on keratin, a protein found in skin, hair, and nails. The most common culprit in cats is Microsporum canis, which is also zoonotic—meaning it can spread from animals to humans. Although the term “ringworm” suggests a ring-like appearance, that’s not always how it shows up in cats. Symptoms can range from subtle to severe, depending on the cat’s immune system, age, and overall health.
Kittens, senior cats, and those with weakened immune systems are more likely to show pronounced signs of infection. The infection spreads through direct contact or through contaminated environments—think bedding, grooming tools, or even furniture. Because ringworm in cats is so contagious, early detection and treatment are important for protecting your household and any other pets.
Recognizing the Early Signs of Ringworm in Cats
Ringworm can be subtle at first, which is why it often goes unnoticed until symptoms become more obvious. Understanding what to look for can help you identify a problem early and seek veterinary care.
Patchy Hair Loss and Scaly Skin
One of the most common signs of ringworm is circular areas of hair loss. These patches may have a red or gray center with scaly or crusty skin. The lesions typically appear on the head, ears, and front legs, but they can develop anywhere on the body.
Excessive Grooming or Scratching
Cats with ringworm may groom or scratch more than usual. Overgrooming in response to irritation can lead to further hair loss and inflammation.
Changes in Nail Beds
In some cases, ringworm affects the claws and the skin around the nails. You may notice brittle or misshapen claws, along with swelling at the base of the nail. These changes are less common but still important signs to watch for.
Skin Lesions That Don’t Heal
If you notice any skin lesions that fail to heal or appear to spread, schedule an exam with your veterinarian at Advanced Animal Care. Persistent skin changes may point to an infection like ringworm in cats. Prompt treatment can prevent complications and help protect other pets in the home.
How Ringworm Spreads Among Cats and Other Pets
Ringworm is extremely contagious. It spreads through direct contact with an infected animal, contaminated bedding, grooming tools, or even shared surfaces. Spores can survive in the environment for months, making ringworm challenging to control once it takes hold.
Contaminated Environments
Cats don’t have to come into contact with another animal to catch ringworm. They can pick up spores from furniture, carpet, or scratching posts. Ringworm’s environmental persistence makes it more difficult to contain without veterinary guidance.
Zoonotic Risk: Transmission to Humans
Ringworm is zoonotic—meaning it can spread from animals to people. Children, seniors, and those with compromised immune systems are at higher risk of infection. It’s essential to treat ringworm promptly and thoroughly to reduce exposure risks at home.
Diagnosing Ringworm in Cats
Because ringworm mimics other skin conditions, a physical exam alone may not provide enough information. Your veterinarian may recommend diagnostic tests to confirm the cause and determine the best treatment approach.
Wood’s Lamp Examination
Some strains of ringworm fluoresce under ultraviolet light. Your veterinarian may use a Wood’s lamp to scan affected areas. However, not all fungal strains glow, so additional testing is usually required.
Fungal Culture and Skin Scrapings
A fungal culture involves collecting hair or skin samples from affected areas and growing them in a lab to identify the fungus. Skin scrapings may also be taken to rule out other conditions. These tests help ensure your pet receives the correct diagnosis and treatment.
How Is Ringworm in Cats Treated?
Treating ringworm takes time and a consistent approach. Your veterinarian will recommend a treatment plan based on the severity of the infection, the number of pets in the household, and the potential for transmission.
Topical Antifungal Medications
Topical treatments, such as medicated shampoos, ointments, or dips, can help clear up mild infections. Your veterinarian will provide guidance on how to apply the medication and how often to bathe your cat.
Oral Antifungal Medications
More severe cases of ringworm may require oral antifungal medications. These are usually prescribed for several weeks and may be combined with topical treatments for a more effective response.
Environmental Cleaning and Disinfection
Treating ringworm also involves cleaning your home thoroughly. Vacuum frequently, disinfect surfaces, wash bedding, and limit your cat’s access to shared furniture. Since ringworm in cats can survive in the environment for an extended period of time, the cleaning protocol tends to be more extensive.
Preventing the Spread of Ringworm in Multi-Pet Households
If you have more than one cat or other animals in your home, containment and hygiene are key to stopping the spread. Isolate infected pets during treatment and follow your veterinarian’s instructions closely.
Routine Veterinary Checkups
Routine exams allow your veterinarian to spot early signs of skin infections and discuss prevention strategies. Cats that go outdoors, visit grooming facilities, or live in shelters are at higher risk for ringworm in cats.
Managing Pet Supplies and Shared Spaces
Clean or replace grooming tools, bedding, scratching posts, and litter boxes. Even if only one pet shows symptoms, spores can transfer easily from object to object. Environmental hygiene is an important step in managing any contagious condition.
When to Schedule a Veterinary Visit
If your cat shows signs of hair loss, skin lesions, or changes in grooming behavior, contact your veterinarian for an evaluation. Accurate diagnosis is the first step toward helping your pet feel better. Prompt treatment also reduces the risk of spreading ringworm to other animals and people in the home.
