Which of the following animals is NOT a cecal fermenter?

Explanation:
The main idea is where fiber fermentation occurs in hindgut fermenters. In animals classified as cecal fermenters, the cecum is the primary site where microbes break down fibrous plant material. Horses rely on a large cecum for fiber digestion, and rabbits and guinea pigs also depend on the cecum (with rabbits even producing cecotropes to reclaim nutrients). Pigs, while hindgut fermenters, digest mainly in the large intestine with the colon being the primary fermentation chamber, so the cecum is not the main site. Because the pig’s fermentation happens primarily in the colon rather than the cecum, it is not a cecal fermenter.
