[2] The fauces is a part of the oropharynx directly behind the oral cavity as a subdivision, bounded superiorly by the soft palate, laterally by the palatoglossal and palatopharyngeal arches, and inferiorly by the tongue.
Between these two arches on the lateral walls of the oropharynx is the tonsillar fossa which is the location of the palatine tonsil.
The approximation of the arches due to the contraction of the palatoglossal muscles constricts the fauces, and is essential to swallowing.
In this species faucitis is usually caused by bacterial and viral infections although food allergies need to be excluded in any diagnosis.
Treatment is symptomatic and includes broad-spectrum antibiotics and in severe cases where cats are inappetant, corticosteroids (often given as depot forms, e.g. depomedrol) or chemotherapy (e.g. chlorambucil).
