My 6 kg cat just ate about a cup of plain cooked couscous — is that too much for her size?

Short answer

Yes, a full cup is far too much for a cat and will likely cause stomach upset or vomiting. Couscous is safe in tiny amounts, but this volume can swell in her stomach and lead to discomfort, gas, or even a temporary loss of appetite. Check that it was truly plain — no onion, garlic, or salty stock mixed in. Offer fresh water and watch her closely for the next 12 hours. If she vomits more than once, seems lethargic, or refuses her next meal, call your own vet. For future treats, stick to a teaspoon or less.

Couscous — Food safety facts

Plain cooked couscous is safe. Watch for added stock or seasoning.

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

Couscous 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.

Couscous 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.
