Can cats eat crab, and why?
Only a tiny taste of plain cooked crab meat, if any, as it is salty and can cause upset. High salt and possible allergy; avoid shells, seasoning and imitation crab sticks.
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
High salt and possible allergy; avoid shells, seasoning and imitation crab sticks.
If your cat has eaten crab, 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.
