Can cats eat pesto, and why?
Do not give pesto to cats. The garlic is toxic to cats and the oil and salt offer nothing useful.
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
The garlic is toxic to cats and the oil and salt offer nothing useful.
