My 4 kg cat just ate one sesame seed from my bagel — should I be worried?

Short answer

No, one sesame seed is completely safe for a cat. Plain sesame seeds are non-toxic and too small to cause a blockage. Just keep an eye on your cat for the next few hours, and call your own vet if you notice anything unusual.

Plain sesame seeds are safe. Tahini is fine in tiny amounts.

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

Sesame seeds 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.
