Serving advice
Treat fresh catnip as a snack rather than part of the daily ration — the usual ceiling is about 10% of daily calories. Start with one small piece of fresh catnip and watch stools and appetite over the next 24 hours.
Fresh catnip (nepetalactone) is non‑toxic to both dogs and cats. In cats it induces a short‑lasting behavioral response—rolling, rubbing, and mild hyperactivity—but does not cause lasting harm. Dogs may be indifferent. Watch for excessive excitement or brief digestive upset.
Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.
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.
