Causes
Young rabbits respond badly to stress, transport (especially during the post-weaning period), to unidentified noises, to a new environment and to new persons or animals. Modifications of the diet or a diet low in fibers can, furthermore, lead to digestive disorders. Usually, food alone is not the main trigger of diarrhea, but rather its composition, such as a low percentage of crude fiber, too rich in carbohydrates or proteins, too finely ground food or improper watering, or the introduction of a new sort of vegetable or fruit.
Further causes of diarrhea include the administration of drugs or antibiotics (see: “Antibiotics dangerous for use in rabbits”), or the presence of nitrate in the drinking water. Viruses and pathogen bacterial overgrowth of e.g. Corynebacteria sp., Clostridia sp., Pasteurella sp. and Escherichia coli cause enteritis. The occurence of Salmonella sp. is, however, rare in rabbits. The presence of intestinal parasites such as trematodes (flukes), cestodes (tapeworms), nematodes (parasitic intestinal worms), and protozoa (coccidiosis
) can also lead to digestive disorders in rabbits, with onset of stasis and diarrhea.
