Can Cats Eat Olives?

Yes, with caution. Plain, pitted olives are not considered toxic to cats, but they are salty, fatty, and not an ideal food for an obligate carnivore.

Plain olives are usually low-risk, but not a good regular treat

A small amount of plain, pitted olive is unlikely to poison most cats. The bigger concerns are high sodium from brine, stomach upset from fatty foods, and choking or intestinal obstruction from pits or stuffed olive ingredients like garlic or onion, which are especially dangerous to cats.

How urgent is this?

Emergency

Go to the ER now

  • ● Cat is choking, struggling to breathe, or cannot swallow after eating an olive or pit
  • ● Cat ate olives stuffed or seasoned with onion or garlic and is now weak, pale, breathing fast, or collapsing
  • ● Neurologic signs such as tremors, severe lethargy, disorientation, or seizures after eating a large amount of very salty olives or brine
Urgent

See a vet within 24 hours

  • ● Cat swallowed an olive pit or several pits
  • ● Cat ate a large amount of brined olives or drank olive brine
  • ● Cat ate stuffed, marinated, or heavily seasoned olives
  • ● Vomiting, diarrhea, abdominal pain, drooling, or loss of appetite lasts more than a few hours
Monitor

Watch at home, call if it worsens

  • ● Cat ate a tiny piece of plain, pitted olive and is acting normal
  • ● Mild brief stomach upset after a small amount
  • ● One lick of plain olive oil or a small taste of plain olive with no symptoms

How to Safely Feed Olives to Your Cat

Olives should only be an occasional nibble, not a routine treat. Because cats are obligate carnivores, olives do not provide essential nutrition and should stay well under your cat's treat allowance.

  • Only offer plain, pitted olives with no stuffing, marinades, onion, garlic, herbs, or spices
  • Rinse off brine if possible to reduce sodium
  • Offer only a very small amount, such as a tiny piece or one small slice, as an occasional treat
  • Do not give olive pits, which can be a choking hazard and may cause gastrointestinal obstruction
  • Skip olives for cats with kidney disease, heart disease, high blood pressure, pancreatitis, sensitive stomachs, or those on sodium-restricted diets

Common Questions

Are olives toxic to cats?
Plain olives are not generally considered toxic to cats, but that does not make them a good cat treat. Most olives are packed in salty brine, and stuffed or flavored olives may contain onion or garlic, which are more toxic to cats than to dogs.
Why are stuffed or marinated olives riskier for cats?
Stuffed and marinated olives may contain garlic, onion, peppers, cheese, oils, or spices. Onion and garlic can damage a cat's red blood cells and cause Heinz body hemolytic anemia, and rich or spicy ingredients can trigger vomiting or diarrhea.
Can cats eat olive pits?
No. Olive pits can cause choking and may act as a gastrointestinal foreign body. Call your vet promptly if your cat swallows a pit, especially if your cat starts vomiting, stops eating, strains to pass stool, or seems painful.
Can cats have olive oil?
A tiny lick of plain olive oil is usually not toxic, but too much can cause gastrointestinal upset and extra calories. Olive oil is not necessary for a healthy cat and should not be used routinely unless your veterinarian recommends it.
Is this different for cats than dogs?
Yes. While olives themselves are similarly low-risk in both species, cats are generally more sensitive to toxic ingredients often found with olives, especially onion and garlic. Cats also have unique metabolism differences and are less suited to plant-based treats overall, so a food that is merely 'not toxic' is not automatically a good choice for cats.
