Symptoms of bacterial or fungal otitis externa in cats:

1. Initial shaking of the head, scratching of the ears, yellowish serous discharge from the ears, and congestion of the external auditory canal Redness and swelling.
2. When the condition worsens, pustules appear in the external auditory canal, or localized necrosis of the skin occurs, and brown-black, foul-smelling purulent secretions flow out of the ear canal. Because the secretions often adhere to the coat at the base of the ears, the coat may fall off or dermatitis may occur, causing the sick animals to suffer, suffer from loss of appetite, sometimes increase body temperature, and reduce hearing.

Feline-specific and food-sensitivity otitis externa symptoms:

Specifically-related otitis externa is generally more common than food allergies. Symptoms of atopic or food allergy otitis externa may appear earlier than other skin allergies, and the symptoms may occur at the same time, or only the ears may be affected, and are usually bilateral. This type of otitis externa is often followed by bacterial and yeast infections, and atopic allergic otitis externa is particularly likely to cause ear hematoma.

Treatment methods for cat otitis externa:

Cats with severe ear canal infections can undergo bacterial culture and antibiotic sensitivity testing to determine the type of bacterial infection and effective antibiotic treatment . The treatment of allergic otitis is to directly relieve secondary infection, reduce inflammation and remove wax from the ear, and give topical ear medications (antibiotics, steroids, or antifungal agents). If it is a food sensitivity, you need to eliminate the allergic foods first, slowly switch foods to find out the allergic ingredients, or switch to a hypoallergenic hydrolyzed protein diet. Substances in the environment that are likely to cause allergies, such as flowers, grass, and dust, should be minimized.
