Anorexia and Lethargy in a Pet Rabbit
A 3-year-old spayed female lop rabbit is presented for 24 hours of anorexia and reduced fecal output. She is quiet but responsive, with a heart rate of 220 beats/min, respiratory rate of 60/min, and rectal temperature of 37.8°C. The abdomen is tense and mildly painful; no gas is palpable. Oral examination reveals elongated molar crowns with sharp points on the lingual aspect of the lower molars. The owner reports the rabbit has been eating only soft treats for a week. Blood glucose is 5.6 mmol/L, and PCV is 38%. The owner asks whether to syringe-feed at home or start pain medication and motility drugs.
1. What are the priorities in this rabbit's management? Explain why.
Read the worked answer
The rabbit has GI stasis secondary to dental pain and improper diet. Priorities are:
- Analgesia: pain from molar points drives anorexia and ileus. Meloxicam or buprenorphine should be started early.
- Fluid therapy: correct dehydration to support gut motility and renal perfusion.
- Assisted feeding: provide appropriate fibrous food or a recovery diet to stimulate gut motility. Do not force-feed if obstruction is suspected.
- Dental treatment: the sharp molar points need filing or extraction planning; without addressing the cause, stasis will recur.
- Prokinetics: use only after obstruction is ruled out and with analgesia and fluids.
Judgment point: syringe-feeding alone is not enough if the rabbit is painful and dehydrated. Pain control and dental correction are the drivers of recovery.
2. Evaluate the owner's request to syringe-feed at home versus starting medications. What is safe?
Read the worked answer
Syringe-feeding at home can be appropriate if the rabbit is stable, not obstructed, and the owner is willing and able to do it correctly. The owner must be shown how much to feed, how often, and how to avoid aspiration. However, feeding a painful rabbit without analgesia is stressful and may worsen anorexia.
Medications: analgesia is the first priority. Motility drugs such as metoclopramide should not be given if obstruction is suspected; they are adjuncts, not substitutes for pain control, fluids, and dental care. Antibiotics are not routinely indicated unless there is evidence of infection.
Safe plan: start analgesia and fluids in the clinic, confirm no obstruction, then train the owner to syringe-feed and give oral medication at home. Schedule a recheck in 24–48 hours and arrange dental treatment. If the owner cannot comply, hospitalize.
3. What would make you recommend hospitalization instead?
Read the worked answer
Recommend hospitalization if any of the following are present:
- Severe pain, marked lethargy, or inability to eat despite syringe-feeding.
- Dehydration, hypothermia, or cardiovascular instability.
- Signs of obstruction: marked abdominal distension, gas distension, vomiting, or no fecal output with worsening pain.
- The owner is unable to syringe-feed safely or cannot monitor the rabbit.
- No improvement after 24 hours of home care.
Judgment point: home care is reasonable only when the rabbit is stable, the owner is competent, and the underlying dental disease is being addressed. Hospitalization allows IV fluids, injectable analgesia, and close monitoring for obstruction or hepatic lipidosis.
