Your cat can't taste sweet.

Cats lack a functional sweet-taste receptor because the Tas1r2 gene is pseudogenized.

Your cat's sweet-receptor gene has a broken Tas1r2 component, so the TAS1R2/TAS1R3 receptor cannot form. Sugar produces little or no sweet-taste nerve response in cats. The receptor loss is established; the evolutionary reason is often linked to a meat-heavy diet, but that explanation remains an inference. 1
