What it does, and why
The agent is saponins.
Saponins are soap-like compounds that irritate the lining of the stomach and gut on contact.
Vomiting and loose stool within hours, typically resolving once the plant material passes.
Worth watching for. Dehydration in a small animal, or vomiting that does not stop.

| Plant | Family | Water | Difficulty |

Swapping the plant is the only measure that reliably works. Height and hanging baskets buy less time than people expect with a determined cat.
