Reduced Appetite and Digestive Warning Signs in Rabbits

A rabbit that eats less than normal or stops eating needs prompt attention. Rabbits depend on frequent fibre intake and can become seriously ill quickly. Reduced appetite may be caused by dental pain, gastrointestinal slowdown or obstruction, infection, heat stress, urinary pain, toxins, stress or another underlying problem.

Know the rabbit’s normal routine. Check appetite, water intake, energy, posture and droppings every day. Fewer, smaller, misshapen or absent droppings are important warning signs. Other concerning signs include a hunched posture, repeated position changes, tooth grinding from pain, a swollen or tense abdomen, unusual hiding, weakness, diarrhoea, a dirty bottom or refusal of favourite food.

What to do
• Contact a rabbit-experienced veterinarian immediately when eating has stopped or droppings are greatly reduced or absent.
• Keep the rabbit quiet and at a comfortable temperature while arranging care.
• Make hay and water available, but do not delay professional help to try home remedies.
• Record the last confirmed meal and droppings, recent diet changes, medicines and possible access to foreign objects or toxins.
• Transport the rabbit safely in a secure carrier with familiar hay unless the clinic advises otherwise.

Do not force-feed a rabbit with a swollen abdomen, suspected blockage, severe weakness or difficulty swallowing unless a veterinarian has examined the rabbit and told you to do so. Assisted feeding can be valuable in selected cases, but it is not safe for every cause of appetite loss.

Diarrhoea is different from soft cecotropes. True watery diarrhoea, especially in a young rabbit, is an emergency. Soft uneaten cecotropes also deserve investigation because diet, obesity, pain or other disease may prevent normal consumption.

Prevention includes unlimited grass hay, gradual diet changes, clean water, regular observation, safe housing, appropriate exercise and veterinary dental and health assessment. However, good care cannot prevent every illness.
