Short answer

Yes, dried rosemary in small food-grade amounts is safe for cats fed regularly over time. Rosemary extract is actually a common natural preservative used in commercial pet foods, which confirms its safety profile at normal usage levels. A daily or weekly sprinkle of culinary-grade rosemary on your cat's meals should not cause harm, provided the cat has no known herb sensitivity. Stick to modest quantities — your cat's primary nutrition should come from a balanced feline diet, not herbs.

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.
