Bitter: Cats use the bitter receptors on their tongues to detect infection. One of the reasons why they are finicky eaters. Cats eat a varied diet in the wild and this map help them avoid eating something rotten. Highly processed food is not normal cats. They may detect bitter in processed food.

Sweet: Cats cannot detect the taste sweet at all. However, they can taste ATP (adenosine triphosphate). What? That’s an energy rich molecule found in every cell. ATP harnesses sugar and turns it into energy where it is needed, in muscle meat, for example.
