Can cats eat walnuts, and why?
Walnuts are not recommended for cats. High in fat, a choking hazard and may carry harmful moulds.
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.
