My 6-pound cat ate two Cajun crawfish tails; my other cat didn't touch them. What should I do?

Short answer

This is a mild concern, not an emergency. Plain cooked crawfish is safe, but Cajun seasoning contains garlic and spices that can upset a cat's stomach. Watch only the cat that ate them for vomiting, diarrhea, or lethargy over the next day. Offer him some plain water and call your regular vet if you see any signs of trouble.

Crawfish — Food safety facts

Safe to share · Cats · full breakdown on the linked food page

Plain cooked tail meat is safe. Cajun or garlic-butter versions are not.

Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.

Crawfish is not toxic to cats. The real limit is calories, fat and salt, so treat it as a small extra alongside the normal ration rather than a meal in itself.

There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.

Why these cautions matter

Garlic and onion damage a pet's red blood cells and can bring on anaemia. Signs are often delayed for several days, so looking fine straight afterwards does not rule it out.

Rich, fatty food is the classic trigger for pancreatitis, a painful inflammation of the pancreas that usually needs veterinary treatment rather than rest alone.
