Cats cannot detect the taste of sweetness. Cats lack the receptors on their tongues to detect sweet tastes.
Cats have fewer taste buds than humans, and they are not able to detect sweet tastes. Cats have taste receptors for sour, salty and bitter tastes, but they do not have receptors for sweet tastes. Cats also have a heightened sense of smell, which helps them to detect certain tastes that they would not be able to detect through taste alone.
