Short answer
Plain, cooked cod is actually safe for cats and shouldn't cause poisoning. The risk comes from how it's prepared — if it's fried, battered, or seasoned, the high fat, spices, or garlic/onion powder could cause trouble. Signs like vomiting, diarrhea, or abdominal pain from rich food typically show up within a few hours. Since cod itself is safe, just stick to small amounts of plain, boiled fish and watch for any digestive upset, contacting your vet if it occurs.
