What this means for your cat

Cats should not nibble on lemon verbena. The ASPCA classifies it as toxic to cats because of its essential oils, which can irritate a cat's stomach and cause colic. Cats metabolize plant essential oils less efficiently than dogs, so even a small bite warrants attention.

What to watch for

Most likely signs: stomach upset (vomiting, drooling, lack of appetite) and colicky discomfort (restlessness, hunching, hiding). Reactions are usually mild, but a cat that keeps vomiting can dehydrate quickly.

Time window

Exact onset and duration aren't well documented for lemon verbena in cats; essential-oil GI upset typically begins within a few hours of ingestion and resolves once the source is removed.

When to call the vet

Call your vet if vomiting or diarrhea continues past 12 hours, your cat refuses food at the next meal, or you see lethargy or signs of dehydration. Sooner if a kitten, senior cat, or any cat with a known illness is involved.

Sources: ASPCA (no first-aid guidance).

If a pet has chewed or swallowed plant material and is showing symptoms, contact a veterinarian or poison resource immediately. This product is for structured reference, not diagnosis.
