Can cats eat salt, and why?
Salt and salty foods are best avoided for cats. Excess salt can cause increased thirst and, in large amounts, salt poisoning.
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
Excess salt can cause increased thirst and, in large amounts, salt poisoning.
If your cat has eaten salt, 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.
