Cats: ASPCA lists clematis as toxic, and Pet Poison Helpline notes it contains an irritant glycoside that causes oral and GI irritation. The good news for cat owners is that the plant tastes very bitter, which deters most cats from eating much of it.
Look for excessive salivation/drooling, pawing at the mouth, vomiting, and diarrhea. Severity is generally proportional to the amount chewed; mild oral irritation is the most common presentation.
Onset and recovery time are not well documented for clematis specifically; based on similar GI irritants, signs typically begin within a few hours and resolve within 24 hours with supportive care.
Call a vet or ASPCA Poison Control (888-426-4435) if drooling or vomiting persists more than a few hours, your cat refuses to eat or drink, or you suspect more than a tiny taste was swallowed.
Remove any plant material from the mouth and offer fresh water to rinse it out. Do not induce vomiting unless directed by a veterinarian or poison control.
