Abscesses are a common occurrence in rabbits, and form when bacteria enter the skin or a body cavity, and sets up an infection. This causes a pocket of infection to form, characterised by an accumulation of pus. Unlike dog and cat pus, rabbit pus is thick and semi-solid, much like toothpaste. Abscesses that are located around the face are often due to dental disease. The most common signs of a retrobulbar abscess are bulging of the eye, protrusion of the third eyelid across the eye and inability to close the eyelids completely. Abnormal ocular or oculonasal discharge can also develop as a consequence of the eye irritation and the rabbit may show signs of discomfort such as excessive blinking and grinding teeth. In chronic cases, rabbits can continue eating and drinking normally, but often the rabbit will deteriorate as the pain escalates or the dental disease progresses and eventually will stop eating.
