Short answer

Yes, rosemary is safe for cats even with daily feeding. Small amounts are generally well-tolerated, and rosemary extract is commonly used as a preservative in pet foods. Offer it plain, watch for any vomiting or diarrhea, and call your own vet if anything seems off.

Safe in food amounts. Rosemary extract is a common pet food preservative.

Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.

Rosemary is not toxic to cats. The real limit is calories, fat and salt, so treat it as a small extra alongside the normal ration rather than a meal in itself.

There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.
