Crab

Callinectes sapidus
Also known as:crab
CatCaution

A little well-cooked crab meat is usually fine for cats, but shell, gills and gut must all be removed: fragments can injure or block the gut and raw crab carries bacteria and parasites. Crab is also a common allergen, and seasoned dishes suit cats even less.

DogCaution

**Always cook crab through and remove all shell, gills and gut**: shell fragments can injure or block the gut, and raw crab carries bacteria and parasites. Crab meat is also a common allergen, and dressed dishes add alcohol, salt and oil.
