What is Yeast Infection and Thrush?
Candidiasis is a type of fungal infection that primarily affects the skin. The infection forms when there is an overabundance of the fungus Candida albicans. While typically rare in cats, yeast infections can cause your cat discomfort. In serious cases, yeast infections in cats may be related to upper respiratory disease, intestinal and bladder disease, and eye lesions.
Yeast infections in cats are commonly characterized by skin sores on the ears or genitals, but can affect many parts of the body. When the infection is localized to the inside of the mouth or the esophagus, it is usually referred to as “thrush”.
Symptoms of Yeast Infection and Thrush in Cats
The symptoms of yeast infection will vary based on a number of factors, including where the infection is located on the body. You’ll want to make sure that you’re fully aware of any pre-existing conditions your cat may have, as yeast infections can often share the same symptoms as other diseases.
Symptoms of yeast infection can include:
- Diarrhea
- Lethargy
- Frequent itching
- Dandruff and hair loss
- Drooling, if thrush
- Lesions on the skin or eyes
- Excessive amount of earwax buildup
- Redness caused by irritation of the skin
Causes of Yeast Infection and Thrush in Cats
Though Candida albicans occurs naturally in a cat’s body, a yeast infection can occur when the yeast fungus spreads to vulnerable tissue through a wound or open sore on the skin. It is also possible that yeast infections in cats can be caused by a pre-existing condition or a medication or antibiotic regimen that affects the immune system. Antibiotics can cause a bacterial imbalance, which can trigger a yeast infection.
Other causes of yeast infection may include:
- Improper diet
- Thyroid conditions
- Allergic reaction
- Use of a catheter due to an operation
- A side effect of medications for other conditions
- Pregnancy or lactation
- Diseases or drugs that suppress the immune system
Diagnosis of Yeast Infection and Thrush in Cats
If your cat has lesions or sores and is itching more than usual, it may be suffering from a yeast infection. Contact your vet as soon as you notice lesions on your cat’s skin. It is important that you don’t diagnose or medicate at home, as this may lead to additional side effects or interactions with other medications.
While a yeast infection isn’t life-threatening, you’ll want to take your cat to the vet as soon as possible to resolve their discomfort. Be sure to inform the vet of your cat’s symptoms. The vet may also ask you if your cat is on any medications, so be sure to prepare a list of all medications and dosages before you go.
The vet can perform a number of tests in order to diagnose your cat. These include a blood test, a urine sample, a simple swab of the affected area, and/or a biopsy of the lesions. The biopsy is non-invasive as candidiasis tends to affect only the epithelial, or surface, tissue. The vet will then analyze the samples to check for Candida albicans.
Treatment of Yeast Infection and Thrush in Cats
Ointments and Creams
Topical treatments are often prescribed to treat feline yeast infection. These are applied directly to the infected area. Always be sure to wash your hands thoroughly before and after treatment.
Shampoo
Your vet may prescribe specially medicated shampoos that will help treat your cat’s yeast infection. These shampoos may contain miconazole nitrate, ketoconazole, itraconazole, or fluconazole. These medications will reduce the presence of Candida albicans and promote healing of the epithelial tissue.
Oral Medication
Oral medications to treat yeast infection are sometimes used in conjunction with topical treatments. These medications are usually prescribed if other types of treatment are unsuccessful or if the cat is long-haired and has a more severe yeast infection.
Injection
In rare cases, your vet may suggest injections to treat your cat, particularly if the yeast infection is a more severe type of fungal infection.
Recovery of Yeast Infection and Thrush in Cats
A normal treatment regimen for yeast infection or thrush in cats usually lasts around two weeks. At the outset, topical treatment for a yeast infection should last no longer than a month. If treatment has lasted more than a month and the infection has not cleared up, you should contact your vet immediately.
In any case, your vet will likely schedule a follow-up appointment. During this appointment, your vet will re-examine your cat, testing once again for an overabundance of Candida albicans.
Persistent candidiasis can be a symptom of another, more serious disease or a possible allergy. In the event that candidiasis is still present despite treatment, your vet may run additional tests to determine if another disease is the cause.
Yeast Infection and Thrush Questions and Advice from Veterinary Professionals
Has Symptoms
My about-to-be-12 year old femal Ocicat was bitten by a very venomous spider - probably a black widow - and was treated at the ER vet, plus home or antibiotics (Augmentin) for several days. I am worried about her having a yeast / candida infection of the gut, tongue, etc. now. Can I give her probiotics (meant for humans) or is there something else tht the vet can give her on follow up? She will *not* eat yogurt. Thank you!

1 cat spent an inordinate amount of time licking the inside of cat 2's ears. C2 ears smell AWFUL! Like soured dough. Shortly after this, C1 started regularly drooling (new) & his breath began to smell like her ears. Drooling got worse - thick, clear, ropey. He began struggling to eat & drink. Lost weigh rapidly, dehydrated. Local vet essentially blew me off, blaming drool on stress of car ride, & tells me it's feline diabetes. Same person thought a broken scrap of dry cat food found in the carrier was my cat's tooth until looking in cat's mouth to see no missing teeth. Cat's mouth is also mostly white coated. To say I'm displeased is putting it lightly.
How did you get rid of the thrust. And get your cat to start eating again? Get well!!

My cat has a bad smell and discharge coming from her rear end. Smells like a yeasty substance and she tried to lick it off my bedding. I’m worried but she seems fine other than the bad smell

I have a female tuxedo cat, 3 years old. The other day I gave her a bath, and since then she hardly eats, I don't see much number 2 in her box, and there's a fair amount of clear discharge from her vagina that wetens her tail and upper legs, she seems to be in pain, and growls about it, and my wife believes she has a yeast infection. What should I do?

My 5 year old cat has always had areas on her body that are missing hair. I sleep with her in my bed and she has her pillow right next to me,lined up next to my chest. She cuddles with me, with her head and front paws resting in my hands Her bottom is snuggled up in the pit of my arm, or next to my chest so it is always being kept warm. I have been noticing an odd odor. She is very meticulously cleaning her body. Could she have a yeast infection from keeping her bottom too warm?

My 4 year old cat has been diagnosed as having Feline Immunodeficiency Virus even though he has had all of his vaccinations. Secondary is yeast in his blood. What would be a typical treatment plan for this situation?

In the clinical trial it was shown that the FIV vaccine (FEL-O-VAX) was effective in 82% of cats (four out of five cats), also there is no diagnostic test to differentiate between cats protected by the vaccine and cat naturally infected. Treatment for any infection should be aggressive and carried out by your Veterinarian, additionally FIV positive cats should be kept indoors and not allowed to mix with other cats.
