Short answer

First, stay calm and remove any remaining fennel from your cat's reach. Fennel is non-toxic to cats, so a small nibble is unlikely to cause harm. Next, check your cat's mouth for any large, fibrous pieces that might be stuck. Offer a little fresh water to help wash it down. There's no need to induce vomiting. Simply keep an eye on your cat for the next few hours for any unusual signs like gagging, drooling, or vomiting, though these are not expected with such a small amount of a safe vegetable.

The bulb and fronds are safe in small amounts.

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

Fennel 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.
