Cause

• Food allergies, hormonal abnormalities and excessive moisture are the main causes of yeast ear infections in cats.
  
  

Effects

• Cats with an ear infection often shake their heads and scratch at their ears, resulting in inflammation. The yeast infection may also produce a foul odor and a yellowish or black discharge.
  
  

Identification

• To identify a yeast ear infection, veterinarians analyze an ear wax sample under a microscope. Your veterinarian may also perform yeast cultures to confirm diagnosis.
  
  

Treatment

• Veterinarians treat yeast ear infections with eardrops, ointments and medications such as Chlorhexidine and clotramizole. Also, regularly flush the cat's ears, typically with a 50/50 white vinegar and water solution, to remove wax. Treatment usually takes two weeks.
  
  

Considerations

• Persian cats are more prone to ear infections than other breeds.
