Frequently Asked Questions
Frequently Asked Questions
Why is kalanchoe toxic to pets?
Kalanchoe contains bufadienolides, which are cardiac glycosides — the same class of heart-affecting toxins found in oleander. They cause vomiting and diarrhea, and in larger amounts can disrupt the heart rate and rhythm. The flowers contain the highest concentration.
How much kalanchoe is dangerous?
A small nibble may cause only mild stomach upset, but larger ingestions can lead to abnormal heart rhythms, weakness, and collapse. Because the cardiac effects are serious, call a vet with the amount eaten and your pet's weight rather than monitoring at home.
What signs should I watch for after kalanchoe ingestion?
Vomiting, diarrhea, and drooling are the early signs. With larger amounts, watch for weakness, an irregular or abnormal heart rate, and collapse. Heart symptoms mean this is an emergency — call a vet immediately.
