Can cats eat leek, and why?
Leeks are toxic to cats and must be avoided. Part of the onion family; can cause anaemia even in small amounts.
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.
