My 4 kg cat ate three large raw radicchio leaves two hours ago and is now vomiting — how long do these symptoms usually last?

Short answer

Radicchio is safe, but eating three large leaves is a lot of roughage for a small cat and can cause stomach upset. The vomiting is likely a direct reaction to the unusual volume and fiber. This kind of dietary indiscretion usually causes symptoms for 12 to 24 hours. Offer small amounts of water to prevent dehydration, but withhold food for about 6 hours to let her stomach settle. If the vomiting continues beyond a day, she becomes lethargic, or refuses water, call your own vet. For future treats, a tiny piece of radicchio is plenty.

Radicchio — Food safety facts

Safe in small amounts.

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

Radicchio 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.

Radicchio 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.
