My cat ate two bites of cooked kohlrabi 4 hours ago and seems fine — how long do I watch her?

Short answer

She's fine — kohlrabi is safe for cats. The 4-hour window is the most critical for a new food, and she's already past it without vomiting or diarrhea. Keep an eye on her litter box for any unusual softness tonight. Offer her regular food and water as normal. If she develops a sudden lack of appetite or any vomiting tomorrow, give your own vet a call.

Kohlrabi — 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.

Kohlrabi 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.

Kohlrabi 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.

The full verdict, portion guidance and serving notes are collected on the Kohlrabi food facts page.
