Is Kalanchoe safe for Cats?
✓ Sources checked by the Eaoae Safety Review · 2026-10-28 · Based on 3 sources
No, kalanchoe is unsafe for cats. Bufadienolide cardiac glycosides cause vomiting, diarrhea, weakness, heart rhythm abnormalities, and possible collapse. As a popular houseplant, it is a frequent culprit in cat poisoning calls.
🚨 Emergency: Yes — contact your veterinarian immediately.
💡 Why
Cats that chew houseplants are the classic kalanchoe victims. The plant's bufadienolides produce GI signs first (vomiting, diarrhea), then the cardiac effects: arrhythmias, weakness, and in severe cases cardiovascular collapse. PPH lists it among the most dangerous houseplants for both species. Because it is so common indoors, prevention -- not treatment -- is the real strategy.
🩺 What to do
- Remove kalanchoe from homes with cats that chew plants.
- Any chewing warrants a vet call given the cardiac risk.
- Watch for vomiting and lethargy.
❓ Common questions
Are all kalanchoe types toxic?
Yes -- all Kalanchoe species and hybrids (mother-in-law plant, chandelier plant, panda plant) contain bufadienolides.
What does it look like in cats?
Drooling, vomiting, diarrhea, and lethargy; severe cases show weakness, irregular heartbeat, and collapse.
How do I keep my cat safe?
Rehome the plant or hang it where the cat absolutely cannot reach; cats are persistent plant chewers.
