Is it okay to feed my 3.5 kg indoor cat a small piece of raw bok choy every day as a treat, or could that cause problems over time?

Short answer

A small piece of raw bok choy occasionally is fine for a 3.5 kg cat, but feeding it daily is not advisable. Bok choy is a cruciferous vegetable that contains compounds which, in large or repeated amounts, can interfere with thyroid function over time. Cats are obligate carnivores, so vegetables should never replace meat-based nutrition in their diet. If you want to offer bok choy, stick to an inch-sized piece no more than once or twice a week and watch for any soft stool or gas. Cut it into small, bite-size pieces to avoid choking, and serve it plain without any seasoning, oil, or garlic.

Bok choy — Food safety facts

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

Safe raw or cooked in small pieces.

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

Bok choy 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.

Bok choy 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.
