1. What Are Yeast Infections in Cats?
Yes, cats can get yeast infections. A yeast infection occurs when there is an overgrowth of yeast on your cat’s body.
Yeast is a type of fungus that naturally resides on the skin and in the ears of cats. Under normal circumstances, the immune system keeps the yeast population in check, preventing it from causing any problems. However, when the immune system is compromised, or when other predisposing factors are present, yeast can multiply excessively, leading to an infection. These infections can be localized or widespread, affecting different areas of the body.

1.1. What Are the Common Types of Yeast Infections in Cats?
The most common types of yeast infections in cats are caused by Malassezia and Candida species. Malassezia pachydermatis is a lipophilic yeast, meaning it thrives in oily environments, making it a common culprit in ear infections (otitis externa) and skin infections (dermatitis). Candida albicans, another common yeast, can cause oral thrush and, less frequently, skin infections.
1.2. Where Can Yeast Infections Occur on a Cat’s Body?
Yeast infections in cats can occur in various parts of the body, each presenting with specific symptoms:
- Ears: Yeast infections are commonly found in the ears, leading to otitis externa.
- Skin: Yeast dermatitis can affect any part of the skin, but it is frequently seen in the skin folds, between the toes, and around the anus.
- Mouth: Thrush, caused by Candida, affects the oral cavity, leading to white plaques and inflammation.
- Urinary Tract: Though less common, yeast infections can occur in the bladder, leading to cystitis.
1.3. Are Yeast Infections in Cats a Medical Emergency?
While yeast infections are not typically considered medical emergencies, they can cause significant discomfort and distress to your cat. If left untreated, they can lead to secondary bacterial infections and chronic skin or ear problems. Prompt veterinary care is essential to alleviate your cat’s discomfort and prevent complications.
2. What Are the Common Symptoms of Yeast Infections in Cats?
Symptoms of yeast infections in cats vary depending on the location and severity of the infection. Recognizing these signs early can help you seek timely veterinary care and provide relief for your feline friend.
2.1. Skin-Related Symptoms
Skin infections are among the most common presentations of yeast overgrowth in cats.
- Itchiness: This is a hallmark symptom of yeast dermatitis. Affected cats will excessively scratch, rub, and lick at their skin, leading to further irritation and potential self-trauma.
- Hair Loss: Constant scratching and licking can cause hair loss (alopecia) in the affected areas.
- Redness: The skin may appear red and inflamed due to the inflammatory response triggered by the yeast overgrowth.
- Skin Bumps: Small, red papules or pustules may develop on the skin’s surface.
- Dry, Flaky Skin: The skin may become dry, scaly, and flaky, resembling dandruff.
- Thickened Skin: In chronic cases, the skin may thicken and develop a leathery texture.
- Chewing or Licking Skin/Paws: Cats may obsessively chew or lick at their paws and other affected areas, further exacerbating the condition.
- Brown Staining on Fur: Saliva staining from excessive licking can cause the fur to turn brown.
2.2. Ear-Related Symptoms
Yeast infections in the ears (otitis externa) are also common in cats.
- Frequent Scratching of Ears: Affected cats will frequently scratch at their ears, often shaking their heads in an attempt to relieve the discomfort.
- Head Shaking: This is a common sign of ear irritation.
- Red, Inflamed Ears: The ear canals and ear flaps may appear red and inflamed.
- Thick, Yellow Ear Discharge: A characteristic sign of yeast otitis is a thick, waxy, yellow or brown discharge in the ear canals.
- Musty Odor: Yeast infections often produce a distinct, musty odor.
2.3. Mouth-Related Symptoms
Thrush, or oral candidiasis, can cause the following symptoms:
- White Plaques in Mouth: The most noticeable sign is the presence of white, cottage cheese-like plaques on the tongue, gums, and inner cheeks.
- Excessive Drooling: The discomfort and inflammation in the mouth can lead to increased salivation.
- Bad Breath: Oral yeast infections can cause foul breath.
- Reduced Appetite: Pain and discomfort can make it difficult for cats to eat, leading to a decreased appetite.
2.4. Other Systemic Symptoms
In some cases, yeast infections can cause more generalized symptoms, especially if they are widespread or affect internal organs.
- Lethargy: Affected cats may become lethargic and less active than usual.
- Diarrhea: In rare cases, yeast infections can affect the gastrointestinal tract, leading to diarrhea.
If you notice any of these symptoms in your cat, it’s essential to consult with your veterinarian for proper diagnosis and treatment. Early intervention can prevent the infection from worsening and improve your cat’s overall quality of life.
3. What Are the Causes and Risk Factors of Yeast Infections in Cats?
Yeast infections in cats occur when the balance of microorganisms on the skin or in the body is disrupted, allowing yeast to overgrow. Several factors can contribute to this imbalance, making some cats more susceptible than others.
3.1. Compromised Immune System
A weakened immune system is one of the most significant risk factors for yeast infections in cats.
- Chronic Diseases: Conditions like feline leukemia virus (FeLV), feline immunodeficiency virus (FIV), diabetes mellitus, and cancer can suppress the immune system, making cats more vulnerable to yeast overgrowth. According to research from the Cornell Feline Health Center, cats with chronic diseases are more prone to opportunistic infections like yeast infections.
- Immunosuppressive Medications: Medications like corticosteroids (prednisone) and cyclosporine, which are used to treat inflammatory and autoimmune conditions, can also weaken the immune system, increasing the risk of yeast infections.
3.2. Skin Trauma and Allergies
Damage to the skin can create an environment conducive to yeast overgrowth.
- Skin Trauma: Wounds, scratches, and abrasions can disrupt the skin’s natural barrier, allowing yeast to penetrate and multiply.
- Allergies: Allergic skin disease (atopic dermatitis) is a common cause of yeast infections in cats. Allergies can cause intense itching, leading to self-trauma and secondary infections.
3.3. Environmental Factors
Certain environmental conditions can also promote yeast growth.
- Humidity: Warm, humid environments can favor the proliferation of yeast on the skin.
- Poor Hygiene: Inadequate grooming and hygiene can create a breeding ground for yeast, especially in skin folds and ears.
3.4. Breed Predisposition
While any cat can develop a yeast infection, certain breeds may be more predisposed due to their anatomical features.
- Breeds with Skin Folds: Breeds with prominent skin folds, such as Persians and Himalayans, are more prone to yeast infections in these areas due to the warm, moist environment.
3.5. Other Underlying Conditions
Various other conditions can indirectly contribute to yeast infections.
- Obesity: Overweight cats may have difficulty grooming themselves properly, leading to a buildup of moisture and debris on the skin.
- Endocrine Disorders: Conditions like hypothyroidism can affect the skin’s health, making it more susceptible to infections.
Understanding these causes and risk factors can help you take preventive measures to protect your cat’s health. Regular veterinary checkups, proper hygiene, and prompt treatment of underlying conditions can significantly reduce the risk of yeast infections.

The first step in diagnosing a yeast infection is a comprehensive physical examination.
- Visual Assessment: Your veterinarian will carefully examine your cat’s skin, ears, and mouth for any visible signs of infection, such as redness, inflammation, discharge, and lesions.
- Palpation: They will also palpate (feel) the affected areas to check for thickening, pain, or other abnormalities.
4.2. Medical History Review
Your veterinarian will ask you detailed questions about your cat’s medical history.
- Symptom Onset and Progression: When did you first notice the symptoms? Have they been getting better or worse?
- Previous Health Issues: Does your cat have any known allergies, chronic diseases, or other health problems?
- Medications: Is your cat currently taking any medications, including prescription drugs, over-the-counter remedies, or supplements?
- Diet: What type of food does your cat eat? Has there been any recent change in diet?
4.3. Diagnostic Tests
To confirm the presence of a yeast infection and rule out other possible causes, your veterinarian may perform one or more of the following diagnostic tests:
-
Skin Cytology: This is the most common and reliable method for diagnosing yeast infections on the skin.
- Tape Impression: A piece of clear acetate tape is pressed onto the affected skin to collect cells and debris.
- Skin Scraping: A dull scalpel blade is used to gently scrape the skin’s surface to collect a sample of cells.
- Microscopic Examination: The collected sample is stained and examined under a microscope to identify yeast organisms.
-
Ear Swab Cytology: This test is used to diagnose yeast infections in the ears.
- Swabbing: A cotton swab is inserted into the ear canal to collect a sample of earwax and discharge.
- Microscopic Examination: The sample is stained and examined under a microscope to identify yeast organisms.
-
Fungal Culture: In some cases, your veterinarian may recommend a fungal culture to identify the specific type of yeast causing the infection. This test involves taking a sample from the affected area and placing it in a special culture medium to allow the yeast to grow. The specific type of yeast can then be identified.
-
Wood’s Lamp Examination: A Wood’s lamp is a handheld ultraviolet light that can be used to detect certain types of fungal infections. While not specific for yeast, it can help rule out other fungal infections, such as ringworm.
-
Blood Tests: Blood tests may be performed to evaluate your cat’s overall health and identify any underlying conditions that may be contributing to the yeast infection, such as diabetes or immune system disorders.
-
Urinalysis: If a urinary tract infection is suspected, your veterinarian may perform a urinalysis to check for the presence of yeast or other abnormalities in the urine.
By combining these diagnostic methods, your veterinarian can accurately diagnose a yeast infection in your cat and develop an appropriate treatment plan.
5. How Are Yeast Infections in Cats Treated?
Treating yeast infections in cats involves addressing both the yeast overgrowth and any underlying conditions that may be contributing to the problem.
