Can cats eat weetabix, and why?
A nibble of plain Weetabix is not toxic but offers nothing useful for cats. Cats need meat-based protein; cereal adds only empty carbs.
Cats are obligate carnivores: they must get most of their nutrition from meat and need nutrients such as taurine that only animal products provide. They lack some enzymes for processing plants and carbohydrates, so fruit and veg offer little benefit and can upset their stomach; many cats are also lactose intolerant.
Warning — what to watch for
Cats need meat-based protein; cereal adds only empty carbs.
