My cat ate a whole crab leg, is that too much crab?

Short answer

A whole crab leg is too much crab for a cat. While the cooked meat itself isn't toxic, that amount can cause stomach upset like vomiting or diarrhea. The main risk is the sharp shell, which can cause serious internal injuries. Offer your cat a bland diet and call your own vet if you see any signs of discomfort or trouble passing stool.
