My 5 kg cat ate a large piece of plain, cooked bass 2 hours ago and seems fine — how long should I monitor her, and what signs would mean a vet visit?

Short answer

Plain, cooked bass is safe, so serious toxicity isn't the concern. Monitor your cat for about 24 hours. The main things to watch for are signs of an upset stomach or a bone fragment causing trouble. If she starts vomiting repeatedly, has diarrhea, seems lethargic, or refuses her next meal, call your vet. Also check her mouth gently for any small bones that might be stuck in her gums. As long as she's acting normal, eating, and using the litter box, you can relax after a day.

Bass — Food safety facts

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

Cooked bass is safe, and a good lean protein.

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

Bass 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.

Bass can stay on the rotation, but only as an extra mouthful: keep the rest of the day's food unchanged and watch the litter box and how quickly they finish the next meal.
