My cat nibbled some parsley garnish off a holiday party platter — is that harmful for a senior cat?

Short answer

No, that's perfectly safe. Parsley is non-toxic to cats, and a small nibble of the fresh garnish is harmless. In fact, tiny amounts are sometimes used in pet products as a breath freshener. The bigger concern with party platters is other foods that might have been on there, like onions, garlic, or rich dips, which are dangerous. Since your cat is older, just keep an eye out for any unusual lethargy or digestive upset over the next day, but the parsley itself is not a worry.

Safe, and a little is even used as a breath freshener for dogs.

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

Parsley 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.
