Why does lions eat grass?
Hi there…the big cats don’t eat grass as a source of nutrients rather eating grass has a purely mechanical function. Ingested blades of grass trigger regurgitation of indigestible or hard to digest matter, like the cats’ own hair swallowed during grooming, or fur and bones of prey. Expelling this matter through regurgitation, similar to birds of prey, is safer than allowing it to pass through the digestive tract where it could possibly cause a blockage. Big cats normally will eat the entire animal they capture. Many of their “kills” were herbivores (plant eaters), and cats ended up eating a lot of grass and plants that were in the stomachs and intestines of these animals.
