There are many causes of life-threatening illness in rabbits and good nursing, palliative treatment and supportive care are important aspects of their treatment. Rabbits hide signs of serious disease and may be in a critical state before they are presented for veterinary treatment. Emergency care is often needed and an assessment of the rabbit's condition is necessary to decide on appropriate treatment. Radiography and blood sampling are important parts of this assessment. Rabbits are also prone to gut stasis, which is a preventable life-threatening condition that is often a secondary complication of other diseases.
