Is Clematis Toxic to Cats?
Also known as: Traveller’s Joy, Virgin’s Bower, Leather Flower · Clematis spp.
What makes it toxic
Protoanemonin, an acrid irritant glycoside (ranunculin) released from crushed tissue in all Clematis species. It burns the mouth and inflames the GI lining.
Warning signs to watch for
Drooling, oral pain, vomiting and diarrhea within a few hours; skin contact with sap can cause mild redness.
What to do if your cat eats it
Rinse the mouth, remove plant material and offer water. Call your vet if vomiting persists beyond a day; most nibbles are self-limiting.
Common questions
Are all clematis varieties toxic, including the climbing garden types?
Yes, every Clematis species carries ranunculin-derived protoanemonin. Color and climbing habit do not change the chemistry.
Is dried clematis in arrangements less dangerous?
Yes — protoanemonin degrades as the plant dries, so dried material is far less irritating. Fresh vines and blooms are the risky form.
