  • Acute otitis. Inflammation can affect the outer, middle or inner ear. In the first case, the ear canal that leads to the eardrum is affected, in the second case, it is the area behind the membrane, in the third case, the cochlea and the auditory nerve are inflamed.

Underlying etiologic are parasites, a foreign body stuck in the ear channel, reduced immunity, hypothermia, activation of bacterial and fungal microflora, urticaria in the auricle. The likelihood of developing otitis is especially high if the cat suffers from pharyngitis, rhinitis, furunculosis or skin inflammation. At the first stage, the outer ear gets inflamed, then the infection spreads to the deeper parts of the organ and eventually purulent otitis develops.

Symptoms and Signs

Pus inside cat’s ears is not the only symptom of a disease. Depending on the cause, you may observe such concomitant symptoms as:

  1. cat has pus in ears treatmentSevere itching that drives the cat to scratching and rubbing mercilessly the sore spot or tilting its head oddly.

  5. Wool in the affected area begins to shed.
  6. The general condition of the pet worsens: it may have fever, low appetite, unquenchable thirst, lethargic appearance.

Pus consists of bacteria, white blood cells and protein antibodies, the appearance of which contributes to the generation of the pathogenic microflora. Purulent discharge may be of black, brown, greenish, yellowish colors. When oozing it dries, forming crusts on the cat’s coat. If the inflammation is complicated by parasitic invasion, the discharge becomes darker, sometimes almost black. If a cat has yellowish-green pus oozing from its ear, it most certainly indicates the fungal nature of the disease.

With otitis, concomitant symptoms are fever, earache, general loss in strength, redness and swelling of the affected area. If there is a deformation of the eardrum, the animal’ hearing worsens instantly. Spreading of the infection deeper in the organ can result in total hearing loss, coordination disorder, and facial nerve paralysis. The latter is manifested in in the sudden asymmetry of the cat’s muzzle, sagging of an ear and/or the corner of the mouth.

Curative Treatment

Treatment measures will depend on the stage of the inflammatory process as well as its causes. Both can only be determined by a veterinarian after conducting laboratory tests. The causative agent is usually identified by taking a smear.
