Can cats eat breakfast cereal, and why?
Breakfast cereals are sugary and unsuitable for cats. High sugar offers nothing useful and some varieties contain toxic chocolate or raisins.
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
High sugar offers nothing useful and some varieties contain toxic chocolate or raisins.
If your cat has eaten breakfast cereal, don’t wait for symptoms — contact your vet immediately, or call the Animal PoisonLine on 01202 509000 (24/7, UK). Signs of a problem can include vomiting, diarrhoea, drooling, lethargy, tremors or loss of appetite.
