Can cats eat hazelnuts, and why?
Hazelnuts are not recommended for cats. Too fatty with no benefit and a choking risk.
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.
