Short answer
A tiny taste of olive oil is safe for cats and won't cause poisoning. Upset stomach signs like mild vomiting or diarrhea could appear within a few hours if your cat's stomach is sensitive. These signs are usually brief and resolve on their own. Just keep an eye on her for the next day and call your own vet if anything seems off.
