Normal chest radiographs can be challenging to evaluate and easy to over interpret in the rabbit. The thoracic cavity is small relative to the abdomen, and the heart takes up a large portion of the thorax. The cranial border of the heart is less distinct due to the presence of the thymus, which persists throughout the life of the rabbit. The cranial lung lobes are small and are obscured by a wide mediastinum. The caudal lung lobes have a pronounced vasculature. Additionally rapid breathing makes it difficult to obtain an inspiratory film unless the rabbit is anesthetized and intubated.
With proper care, pet rabbits can live long, happy lives. In this client education handout, we explore the aging changes that can be expected in the senior house rabbit including common health problems. Veterinary screening as well as home care of the geriatric rabbit are also explored.
