Kalanchoe is a common, beautiful houseplant with hundreds of flowers (which range in color from yellow to orange, pink, or red). This plant is also known by several other names including Devil’s Backbone, Mother-of-Millions, and the Chandelier plant. Kalanchoe does belong to a group of plants that contain cardiac toxins (bufadienolides). However, ingestion by dogs and cats most often results in gastrointestinal irritation or upset. If a large enough amount is ingested there may still be risk for more severe signs including changes in heart rate and rhythm, weakness, and collapse.
