Is Indian Hemp Toxic to Cats?
Also known as: Dogbane, Amy Root, Hemp Dogbane, Rheumatism Root · Apocynum cannabinum
What makes it toxic
Cardiac glycosides similar in action to digoxin, present throughout the plant and most concentrated in the root and white latex sap. They interfere with the heart’s electrical system and severely irritate the gut.
Warning signs to watch for
Drooling, vomiting, diarrhea, dilated pupils, weakness and a slow or irregular heartbeat, progressing to collapse, seizures and dangerous arrhythmias in serious cases.
What to do if your cat eats it
Treat any meaningful ingestion as an emergency. Get to a vet promptly for ECG monitoring and decontamination, and bring a sample of the plant so the glycoside exposure is recognized fast.
Common questions
How is Indian hemp different from true hemp?
Despite the name, it is unrelated to cannabis — it is a dogbane with white milky sap and small bell-shaped flowers, and its danger is to the heart, not the mind.
Is the sap dangerous on fur or skin?
The latex irritates skin and mucous membranes, and a cat that gets sap on its coat will groom it off. Wipe the fur with a damp cloth and call your vet.
