Temporary Selective Anorexia ---------------------------- Some pet rabbits occasionally refuse to eat alfalfa pellets. Affected rabbits usually continue to eat other items in their diets. This condition occurs most often in response to stress, such as that associated with inadequate husbandry or sudden environmental changes. Affected rabbits may continue to refuse to eat pellets for weeks. Old or spoiled (rancid) pellets will also be steadfastly refused. This condition is diagnosed indirectly. Physical examination of the rabbit reveals nothing abnormal, and laboratory tests on blood samples are normal. Other causes of inappetence (such as hairball formation) must also be ruled out.
