My 4 kg cat ate a large handful of cooked celeriac two hours ago — what should I watch for during recovery, and what would the vet check?

Short answer

Watch for vomiting, diarrhea, or a loss of appetite over the next 24 hours — that's the main risk with a large portion of any unusual vegetable. Celeriac itself is safe, but it can cause mild digestive upset if she's not used to it. If you do take her to the vet, they'll likely just do a physical exam, feeling her abdomen for any discomfort or bloating. They probably won't need blood tests unless she shows severe signs like repeated vomiting or lethargy. Offer her small amounts of her regular food and plenty of water, and call your own vet if she seems off her food for more than a day.

Celeriac — Food safety facts

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

Peeled and cooked, in small pieces.

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

Celeriac 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.

Celeriac 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.
