Shell and claw fragments cut or block a cat's gut just as easily, and raw lobster carries bacteria and parasites, so it must be cooked and shelled; lobster is a common allergen and a cat can react severely, so start with a tiny amount.

DogCaution

**Hard shell and claw fragments can cut or block the gut** and cause foreign-body emergencies; raw crustaceans carry bacteria and parasites so lobster must be cooked through, and it is a common allergen, while butter or cheese versions add fat and alliums.
