My 3 kg cat munched through half a cup of raw zucchini today — could that upset her stomach?

Short answer

That amount is safe for a 3 kg cat, though the high water and fiber content could cause a loose stool or mild vomiting. Stick to plain, unseasoned zucchini and cut it into bite-sized pieces to keep portions small and manageable. Watch her over the next 24 hours for any signs of an upset stomach, and call your own vet if she vomits repeatedly, seems lethargic, or won't drink water.

Zucchini — Food safety facts

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

Safe raw or cooked, plain. Cut into pieces to prevent choking.

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

Zucchini 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

Raw animal protein carries Salmonella and E. coli risk, and those bacteria can spread to the people in the household too.

Zucchini 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.
