Can cats eat olives? 🫒
Plain olives are not toxic to cats, and some cats are drawn to them, but most olives are cured in salty brine, which is the problem — too much salt is unhealthy, and pits are a choking hazard. A tiny bite of plain, pitted, unsalted olive is the most to offer.

Why this answer
The olive fruit itself carries no feline toxin, and its compounds even attract some cats much like catnip, but table olives are packed in salt brine, and excess sodium is unhealthy and in large amounts can cause salt toxicity. The pit is also a choking and obstruction risk, so olives are a caution food best limited to a tiny plain bite.
Watch for
Increased thirst and urination from the salt
Vomiting or diarrhea after a salty or large serving
Choking or blockage risk if a pit is swallowed
How much is okay
At most a tiny piece of plain, pitted, unsalted olive, rarely — never a whole brined olive or several at once.
Serve it safely
If you share olive, use a small piece of plain, pitted, unsalted flesh.
Skip brined, marinated, or stuffed olives, which are very salty.
Keep pits away, as they can choke or block a small cat.

Answer card
No food checked yet.
Type what your cat is eyeing — or already stole — and the answer lands right here, without leaving the page.
Remove access. Take the food away and move your cat to another room.
Note the facts. What was it, roughly how much is missing, and when? Keep the packaging.
Call before symptoms. For chocolate, onion, garlic, grapes, raisins, alcohol, or anything sugar-free (xylitol), call a hotline or your veterinarian now — early treatment is easier and cheaper.
Never do this
Do not induce vomiting, feed milk, salt, or oil, or wait overnight to "see how it goes". Signs of chocolate or Allium poisoning can take hours to days to appear.
Go to an emergency vet immediately if
Your cat is collapsing, twitching or seizing, struggling to breathe, drooling heavily, vomiting repeatedly, or wobbly on their feet.
