Baby rabbit eating grass
-
Although it is often recommended that young rabbits should not eat any leafy green foods until they are 6 months old, the advice doesn't make sense. It may apply to rabbits kept in crowded conditions with a low fibre diet and many environmental pathogens but for rabbits with access to leafy green plants, it does not apply. Wild rabbits start to eat grass and other plants as soon as they emerge from the nest.

Gastric dilation

Gastric dilation is a feature of intestinal obstruction. The stomach can be grossly distended with gas and fluid so it becomes inflamed

Hepatic lipidosis
-
Hepatic lipidosis is the end point of untreated gut stasis. Fat is broken down as an energy source and is broken down by beta-oxidation in the liver. A metabolic bottleneck occurs and ketoacidosis is the result. Affected rabbits die from liver and/or kidney failure. Disseminated intravascular coagulopathy may occur. Gastric ulceration is another feature of untreated gut stasis. This image shows the appearance of the liver and stomach of a rabbit that died from hepatic lipidosis: the liver is very pale and the dark areas on the stomach are ulcers. The primary problem was a dental spur.

Hepatic lipidosis
-
This image shows the liver of a rabbit that died with hepatic lipidosis. She died a few hours after admission, despite intravenous fluids and other supportive treatment. She was ataxic and hypothermic with a low blood glucose (4.2 mmol/l) on admission. Her urine was acidic on a dipstick due to ketoacidosis. The rabbit had undergone radical dentistry at another practice 4 days earlier and had not eaten since she was discharged on the day of dentistry.

Small intestinal tympany
-
If the small intestine becomes occluded by a foreign body (often a pellet of compressed fur, yellow arrow), the stomach (white arrow) and small intestine that is proximal to the obstruction (turquoise arrow) become dilated and tympanitic and the intestine that is distal to the obstruction is collapsed and empty.
