What the ASPCA says about Kalanchoe
The American Society for the Prevention of Cruelty to Animals (ASPCA) lists Kalanchoe spp. as toxic to cats and dogs. The plant belongs to the Crassulaceae family and is also commonly known as Mother-In-Law-Plant, Devils Backbone, Chandelier Plant, and Mother of Millions.
The toxic principles identified in the plant are bufadienolides. According to the ASPCA, the clinical signs of poisoning in pets after ingesting Kalanchoe include:
- Vomiting
- Diarrhea
- Abnormal heart rhythm (rare)
The entire plant is considered toxic, so any part of it, including the leaves, stems, and flowers, can be harmful if eaten by a cat or dog.
What this means for a home with pets
Having a Kalanchoe plant in a home with cats or dogs requires careful management to prevent accidental ingestion. Pets, especially younger or more curious ones, may be tempted to chew on the leaves or flowers. Because the plant is toxic, even a small amount could cause a negative reaction.
The most common outcome of a pet eating Kalanchoe is gastrointestinal upset, such as vomiting and diarrhea. While the risk of serious cardiac issues is low, it is a possibility that pet owners should be aware of. The presence of bufadienolides means that any consumption of this plant should be taken seriously.
Keeping pets and this plant apart
The most effective way to prevent Kalanchoe poisoning is to ensure pets cannot access the plant. Place it in a room that is off limits to your cats and dogs. Alternatively, position it on a high, stable shelf that your pets, particularly athletic cats, absolutely cannot reach.
Supervising your pets around any houseplant is always a good practice. Never leave them unattended in a room with a potentially toxic plant. When introducing new plants into your home, always check their toxicity to pets beforehand. Reading the plant’s label and researching its name can help you make safe choices for your household.
When to call your vet
If your pet chewed or ate part of this plant, call your veterinarian or an animal poison control line. Note which plant and which part, how much may be gone and when, and take a photo or a piece of the plant with you.
