Otitis Externa in Cats: Symptoms and Treatment

Otitis externa in cats refers to inflammation of the pinna and external ear canal, usually caused by bacteria or fungi. The most common pathogens include Staphylococcus intermedius, Proteus mirabilis, and Pseudomonas aeruginosa. Primary otitis externa is uncommon in cats; it generally occurs when changes in the ear canal environment make it more favorable for bacterial or fungal growth.
