A rabbit's caecum is large, about twice the length of the abdominal cavity and 10 times the capacity of the stomach, 40% of the entire alimentary tract. It is folded into four parts that flex upon each other. It is thin-walled. Visible on the external surface is a spiral constriction that runs 20-30 times around the caecum. This is related to the folding of the mucosa internally. | A rabbit's caecum is large, about twice the length of the abdominal cavity and 10 times the capacity of the stomach, 40% of the entire alimentary tract.
