Only one of my two cats ate thin radish slices while the other did not — should I monitor both?

Short answer

You do not need to monitor both cats equally, because only the one who actually ate the radish is at any real risk. Thinly sliced radish is generally safe for cats, though very spicy varieties can occasionally cause mild stomach upset. Watch the eating cat for loose stool or a softer appetite over the next day, and if she seems normal, there is nothing else to do. The cat who did not eat any radish does not need any special observation or care.

Radish — Food safety facts

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

Safe in thin slices. Very spicy radishes can upset the stomach.

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

Radish 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.

Radish 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.
