Although a cat only has 475 taste buds, while humans have 9,000, it has unique papillae to make up for it. Its tongue is covered with numerous small projections that hook downwards, giving it a rough, sand-papery feel. The papilla helps them scrape meat off bones and hold their prey. Cats also have problems tasting salty and sweet food since their taste receptors favor high-fat and high-protein tastes.
