Tigers have a shorter small intestine compared to cows. The length of the small intestine differs in various animals depending on the

The length of the small intestine is primarily determined by the kind of food an animal consumes. Herbivores, such as cows, eat plant-based diets rich in cellulose. Cellulose is a complex carbohydrate that is difficult to digest and requires a longer time for breakdown by symbiotic bacteria; thus, a longer small intestine is necessary to provide sufficient surface area and time for complete digestion and nutrient absorption. In contrast, carnivores like tigers consume meat, which is relatively easier to digest and absorb compared to plant matter. Consequently, carnivores have a significantly shorter small intestine. This biological variation is a specific evolutionary adaptation to the dietary requirements of the species.
