The caecum is the beginning pouch area of the large intestine and is used for digestion of high fiber materials and often serve as storage zones for cellulose digesting bacteria. Since the area is larger the time to fill and pass material is longer.
Source(s):http://en.wikipedia.org/wiki/CecumThe length of the caecum in rats typically ranges from about 4 to 7 centimeters. This structure serves as a fermentation chamber for digesting fibrous plant material. The size can vary slightly depending on the specific strain of rat and their diet. Overall, the caecum plays a crucial role in the rat's digestive system.
The human organ that corresponds to the caecum is the appendix, which is a small pouch attached to the caecum at the beginning of the large intestine.
The importance of the caecum depends on the species. For carnivores and omnivores (such as humans and dogs), the caecum is not important. For herbivores, like the horse, the caecum is important because it houses bacteria that help it breakdown food (eg. cellulose).
The animal with the largest caecum is the kangaroo. The caecum is a pouch in the digestive tract that aids in the digestion of plant material by fermenting it with the help of bacteria. In kangaroos, the caecum is well-developed to efficiently process the plant-based diet they consume.

A caecectomy is the surgical removal of the caecum.
The sheep's caecum is quite big and this is what makes it possible for sheep to digest fiber. This is a large pouch that is found at the end of the large intestine.

Caecum
Humans do not need a caecum because our diet has evolved to include a wide variety of easily digestible foods, reducing the necessity for the fermentation of plant material that the caecum facilitates in some herbivorous animals. While the caecum plays a role in gut health and the immune system, humans can maintain digestive health without it. Additionally, the appendix, a vestigial structure in humans, may still provide some immune functions, indicating that while the caecum is less critical, some related structures may retain some utility.
