Can cats eat cornflakes, and why?
Cornflakes are salty and sugary and offer nothing useful for cats. Added salt and sugar are unhealthy for an obligate carnivore.
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.

Added salt and sugar are unhealthy for an obligate carnivore.
