Cats can eat olives in very small quantities, and olives are generally not toxic to them. Some cats are attracted to olives because green olives contain a compound similar to the active ingredient in catnip, causing playful or silly behavior. However, olives should only be given as an occasional treat because they are high in sodium and fat, which can be harmful in larger amounts. Avoid olives with pits or harmful additives like garlic or onions, and never feed them in large quantities to prevent health risks such as sodium poisoning or upset stomach. A small piece less than a whole olive a couple of times a week is considered safe for cats that have previously shown no adverse reactions.
