Diagnosis of Loss of Appetite in Rabbits

Your veterinarian will perform a full clinical examination on your rabbit and carefully examine him for signs of underlying conditions that may be causing anorexia. The following may indicate the cause:

  • Excessive salivation or malocclusion may be noted which may suggest dental disease to be the cause
  • There may be an abnormal amount of gas or abdominal masses on palpation
  • Signs of respiratory infection on chest auscultation may be evident
  • If your pet is female the vulva should be carefully examined for discharge which may suggest pyometra
  • Your pet’s skin will be examined for signs of infection or dermatitis

Your veterinarian may choose to do following diagnostic tests: 

  • Radiographs to investigate masses, osteoarthritis or other skeletal disorders
  • Blood chemistry which can rule out renal and hepatic disease and provide a health baseline when prescribing analgesia
  • Urine tests to check for urinary tract infections

Treatment of Loss of Appetite in Rabbits

In order to prevent your pet from developing hepatic lipidosis and to maintain gut peristalsis, your veterinarian will initiate treatment for anorexia immediately. Your rabbit may need to be admitted to the hospital for treatment.

Fluid therapy

Fluid therapy may be given to prevent dehydration and rehydrate gastrointestinal contents. Your pet will be encouraged to have fluids orally but may also be given intravenous or subcutaneous fluid therapy.


As anorexia is often caused by pain it is vital that your pet is given analgesia to relieve discomfort. Your pet may be given NSAIDs or opioids for relief. 


Your pet will be offered a selection of foods. If your pet has favorite foods your veterinarian will recommend you bring them to your pet. Fresh fruit and vegetables along with pellets will be offered. Appetite stimulants high in fiber such as parsley, kale, and carrot tops are ideal for your pet. It is likely your pet will require syringe feeding, this will often be performed by a veterinary assistant or nurse. Ideal foods for syringe feeding are pureed pellets with water, pumpkin or banana. 

In some cases, nasogastric tube insertion is necessary to provide nutritional support. The tube is lubricated with anesthetic gel and inserted through the nose into the stomach. Your veterinarian will then check the position of the tube by performing a radiograph. 

The tube can stay in place for several weeks if needed and will be taped in place. It will be flushed with water prior to each feed, providing an excellent source of water. The same mixtures of either ground pellets or pureed vegetables can be fed through this tube.

Recovery of Loss of Appetite in Rabbits

The prognosis for a pet suffering from loss of appetite can be good to guarded depending on how quickly treatment was sought and the underlying condition involved. If stress was the cause, it is important to adjust your pet’s environment to reduce or completely eliminate the stressor. If your rabbit is suffering from disease such as skin infections or abscess, your pet may need further medication and treatment. For chronic health conditions such as arthritis, it is important that you discuss a long-term pain management plan with your veterinarian to alleviate your pet’s discomfort. Support nutrition will also be beneficial.
