Short answer

Coriander itself is safe for cats in small amounts, but you should be very cautious with supplements and commercial treats. The seed oil or dried leaf in a product may be concentrated, and other ingredients like fillers or preservatives could upset your senior cat's stomach. It's always best to check with your vet before giving any new supplement, especially for a cat with an existing health condition like arthritis. Stick to tiny, plain amounts if you do offer it, and monitor for any changes in appetite or digestion.

Coriander — Food safety facts

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

Safe in small amounts, both the seed and the leaf.

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

Coriander 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.

Why these cautions matter

Stone-fruit pits and some seeds release cyanide when crushed, and quite apart from that they are a choking and blockage hazard.
