What is Cat Fungus?
Cat fungus, also known as dermatophytosis or ringworm, is a highly contagious fungal infection of the skin, hair, and nails. It is caused by microscopic organisms called dermatophytes that feed on keratin, the protein found in skin, nails, and hair.
The most common causes of fungal skin infections in cats are three types of fungi: Microsporum canis, Microsporum gypseum, and Trichophyton mentagrophytes. These fungal spores are present in soil and can be easily transmitted between cats, other animals, and humans through direct contact.
Symptoms of cat fungus often include patchy hair loss, redness, scaling, crusting and itchiness. The areas affected by fungal infection will often be circular with broken hairs, giving it a “ringworm” appearance. However, not all infected cats will display ring-shaped lesions.
Treatment usually involves a combination of oral anti-fungal drugs and medicated shampoos prescribed by a veterinarian. All other pets in the household should also be checked and treated. The fungal spores are very hardy and can survive in the environment for more than a year if not properly disinfected.
Cat ringworm is very common, with studies estimating prevalence between 2.7% to 26% in the general cat population. Stray cats and kittens are at a higher risk. While uncomfortable, cat fungus generally clears within a few weeks of appropriate treatment.

Apple Cider Vinegar Benefits
Apple cider vinegar (ACV) has been used for centuries as a natural remedy due to its many health benefits. Research has shown that ACV has potent antibacterial and antifungal properties that can help fight infections.
Studies have demonstrated ACV’s ability to inhibit the growth of common fungal strains like Candida albicans. One study found ACV was effective against Candida strains isolated from the blood of patients [1]. The acetic acid in ACV is believed to be responsible for its antimicrobial effects.
ACV is generally safe for cats when diluted and administered properly. Make sure to dilute ACV before applying it topically or adding it to your cat’s food or water. Too much ACV can upset your cat’s digestive system. Only give your cat ACV under veterinary guidance.
Some other potential health benefits of ACV for cats include:
- May help control dandruff and soothe irritated skin when diluted and applied topically
- Could help with urinary tract health due to antibacterial properties
- May improve digestion and nutrient absorption
Using ACV for Cat Fungus
Apple cider vinegar (ACV) is sometimes used as a natural remedy for treating fungal infections like ringworm in cats. However, there are important considerations when using ACV on cats:
Dilution is crucial, as undiluted ACV can irritate a cat’s skin. A common dilution is 1 part ACV to 1 part water. Some sources recommend 2 teaspoons of ACV per cup of water.[1] The solution should not be stronger than 50% ACV.
Use a clean cloth or cotton ball to gently apply the diluted ACV on the affected areas 1-2 times per day. Avoid getting it in the cat’s eyes or mouth. Treatment may be needed for 2-4 weeks until the infection clears.
Do not apply ACV to open wounds or irritated skin. Stop use if the cat shows signs of skin irritation. ACV has a strong smell that cats dislike, so restrain the cat if needed to prevent them from immediately licking it off.
While ACV is generally safe for cats when diluted properly, it does not treat fungal infections as effectively as prescription antifungal medication. Consult a vet if the infection persists beyond 2-4 weeks of home treatment. ACV should not replace medical treatment for serious or resistant fungal infections.[2]
ACV Treatment Efficacy
While some pet owners may tout apple cider vinegar as an effective home remedy for treating cat fungus, there is limited scientific evidence to support these claims. Most evidence is anecdotal based on pet owner experiences. One study in the journal MKH found that a cat treated with apple cider vinegar showed improved symptoms, with less intense scratching and irritation. However, this was a single case study and does not prove efficacy.
According to a report on Quora by a veterinarian, apple cider vinegar is not an effective treatment for ringworm in cats. It is more likely to just make the cat sticky and uncomfortable without improving the actual fungal infection. There are no major scientific studies demonstrating antiviral effects of ACV for cats.
One laboratory study published in the Journal of Antifungal Activity did find that ACV exhibits antifungal properties against Candida fungal species in vitro. However, this study was not conducted on animals and looked at isolated fungal cultures rather than topical skin infections. More research is needed to determine if ACV has any meaningful antifungal effects when applied on the skin of cats.
Overall, while some pet owners may find ACV helpful, there is limited scientific evidence that it can effectively treat fungal skin infections like ringworm in cats. Consult with your veterinarian before trying home remedies like ACV, as they may not be backed by robust research.
Other Home Remedies
In addition to apple cider vinegar, there are some other natural home remedies that may help treat cat fungal infections like ringworm. Some of the most common include:
Coconut oil – Coconut oil contains fatty acids that have antifungal properties. Rubbing coconut oil directly on affected areas may help kill ringworm fungus and promote healing. Choose organic virgin coconut oil. [1]
Garlic – Garlic has natural antifungal and antibacterial properties. You can try feeding cats raw garlic or applying diluted garlic oil topically. Use caution, as garlic can be toxic to cats in large amounts. Only use small diluted amounts. [2]
Essential oils – Oils like tea tree oil, lavender oil, and lemongrass oil have antifungal properties. Dilute oils well before applying topically. Do not let cat ingest oils. Use minimal amounts and monitor for reactions. [3]
Oatmeal baths – An oatmeal bath can help soothe irritated skin and may have some antifungal benefits. Make a paste with colloidal oatmeal and lukewarm water and apply to affected areas. Rinse after 5-10 minutes. [4]
When to See a Vet
If the symptoms of cat fungus persist or worsen despite home treatment, it’s important to take your cat to the vet. The vet can help diagnose the specific type of fungal infection through skin scrapings and fungal cultures (PetMD). Accurate diagnosis is key to getting the right antifungal treatment.
Your vet may prescribe oral antifungal medication or other treatments that are more effective than over-the-counter options. For example, prescription shampoos like miconazole, ketoconazole, or chlorhexidine (Flat Rock Vet). Topical ointments may also be prescribed. Cats typically need 4-6 weeks of treatment to fully resolve fungal skin infections.
Don’t delay – if symptoms are not improving or the infection is spreading, take your cat to the vet right away. Prescription treatments and close monitoring can help clear up fungal infections and prevent them from worsening.
Prevention Tips
There are several ways to help prevent fungal infections in cats:
Grooming and hygiene – Regularly brushing and bathing your cat can help remove fungal spores and prevent infections from taking hold. Be sure to thoroughly dry your cat after baths. Keeping their bedding, bowls, litter boxes, and living areas clean is also important.
Reduce exposure to infected animals/objects – Don’t allow your cat to interact with stray or infected animals. Avoid used litter boxes, shared grooming tools, or other objects that may spread infection.
Boost immune health – Feed your cat a nutritious diet rich in antioxidants and nutrients to keep their immune system strong. Supplements like fish oil may also help. Reduce stress and provide a calm environment.
Promptly treating minor skin issues, wounds, or other medical problems can prevent fungal infections from developing. Seek veterinary care if you notice any unusual symptoms.
Diagnosing Cat Fungus
There are a few methods vets use to diagnose fungal infections in cats:
Physical exam – The vet will thoroughly examine the cat’s skin, ears, and nails to look for signs of fungal infection like hair loss, redness, scales, crusts, or nail abnormalities. They may take skin scrapings or plugs of affected areas for fungal culture.
Fungal culture – Samples from skin lesions are placed in a special media to allow fungal growth. The specific fungus is then identified under a microscope, which helps determine treatment options.[1]
Wood’s lamp test – This involves using an ultraviolet light called a Wood’s lamp to look for certain fungal infections that may fluoresce under the light. Skin infected with Microsporum canis will glow green.
Vets may also recommend blood tests, urinalysis, biopsies, or x-rays to check for signs of systemic fungal infection spreading internally.
Cat Fungus vs Other Conditions
Cat fungus often gets confused with other skin conditions like allergies or ringworm. However, there are some key differences to look out for.
Allergies usually cause intense itching, redness, and hair loss. The reaction is typically isolated to one area. Cat fungus results in crusty patches and scaly skin across multiple areas [1].
Ringworm is caused by a different fungus than cat fungus. Ringworm leads to round, red lesions with clearer edges. Cat fungus causes fuzzy white/grey patches and thicker scales [2].
Other fungal infections like yeast can also be mistaken for cat fungus. Checking under a blacklight or getting a vet culture test can confirm which fungus is causing symptoms [3].
In summary, while cat fungus may look similar initially to other conditions, a close inspection of the lesion pattern and testing can differentiate cat fungus.
When to Try ACV
Apple cider vinegar can be a helpful addition to your cat’s care plan for fungal infections, but it’s important to use it appropriately and under the guidance of your veterinarian. Here are some instances when ACV may be useful:
Mild Cases
For minor fungal infections that are localized and not spreading, an ACV rinse or spray could provide some relief when used along with topical antifungal creams or shampoos prescribed by your vet. The acidic nature of ACV can help inhibit fungal growth.
In Combination with Other Treatments
ACV shouldn’t be used as the sole treatment, but some vets may recommend it as a complementary therapy in addition to antifungal medication. The vinegar may help soothe itchiness and inflammation when combined with other remedies.
For Preventative Care
Using an ACV rinse occasionally during bathing may help prevent fungal infections from taking hold in the first place. Its antifungal properties can make your cat’s skin a less hospitable environment for fungal growth.
With Vet Approval
Never use ACV on your cat without consulting your vet first. Your vet can advise you on safe dilution ratios and whether ACV is appropriate for your cat’s specific condition. Self-diagnosis and treatment of skin conditions can worsen problems, so veterinary guidance is key.
