Cat Paw Yeast Infection: Symptoms, Causes, and Treatments

Yeast infections in cats can present a variety of symptoms, including greasy skin, hair loss, redness, scaly skin, thickening of the skin, dark spots, smelly discharge, upper respiratory infections, eye problems, intestinal diseases, chest infections, bladder problems, fever, weight loss, anemia, difficulty breathing, coughing, lameness, and disorientation.

Common Types of Yeast Infections in Cats

Several types of fungal yeast infections can affect cats, each causing distinct health issues:


Candidiasis primarily affects the skin and mucous membranes, especially in immunodeficient cats. The symptoms depend on where the infection occurs, such as ear infections, oral cavity issues, and bladder inflammation.

Malassezia Dermatitis

This type of yeast infection is caused by an overgrowth of yeast on the skin and ears of cats, leading to inflammation, itching, and other issues like skin discoloration and unusual discharge.

Caused by inhalation of soil-borne fungal spores, blastomycosis results in symptoms such as skin lesions, fever, and coughing in infected cats.

Blastomycosis Lungs, skin Skin lesions, fever, coughing

Conditions That Increase Susceptibility to Yeast Infections

Cats with underlying health issues, such as allergies, bacterial infections, endocrine disorders, or immunodeficiencies, are more prone to yeast infections. Factors like diet, environmental conditions (humidity and temperature), and even flea allergy dermatitis can contribute to the development of yeast infections.

Symptoms and Diagnosis

Yeast infections can affect various parts of a cat's body, such as the skin, ears, lungs, and gastrointestinal tract. Common symptoms include scratching, inflammation, skin discoloration, unusual discharge, and sometimes a foul odor. It is important to contact a vet as soon as symptoms like lesions are noticed on the cat's skin. Diagnostic methods include blood tests, urine samples, swabs of affected areas, and biopsies of lesions to check for the specific microorganisms causing the infection.

Treatment and Prevention

Treatment options for yeast infections in cats typically involve antifungal medications, both topical and oral. Natural remedies like coconut oil and probiotics may also be recommended. Early treatment is crucial to preventing potential complications, such as permanent hearing loss or internal organ damage. To prevent yeast infections, maintaining pet hygiene, regular grooming, and dietary adjustments can be helpful. Environmental decontamination and consistent follow-up exams with a veterinarian are also essential for monitoring progress and ensuring resolution of the infection.
