Can Cats Eat Olives?
Caution — olives are not toxic to cats, but the brined version is a real salt load in a small body. Some cats react to olives like catnip; that interest is harmless, but salted olives should not be given.

Why are cats drawn to olives?
Some compounds in olives (isoprenoids) are structurally similar to the nepetalactone in catnip, so some cats roll on, lick, and play excitedly with olives. The reaction itself is harmless — the problem is that the olive is salty.
If you share any: plain, unsalted or well-rinsed, pitted, and no bigger than a fingernail. Olives with vinegar, garlic, or spices, and olive paste, are excluded.
Watch for these signs
- Excessive thirst (salt)
- Vomiting, diarrhea
- Gagging (pit)
If you notice any of these, contact a veterinarian without waiting.
Frequently asked questions
My cat reacts to olives like catnip — is that normal?
Yes, it is a known effect: some olive compounds resemble those in catnip. The reaction is harmless, but do not turn olives into a treat — the salt is the real issue, and catnip is the safer alternative.
Are olive pits dangerous for cats?
Yes — they pose choking and obstruction risks in a small jaw and narrow gut, and because they roll they can be mistaken for toys and swallowed. Put pits in a covered bin.
