Yes, kalanchoe plants are toxic to cats, and they should be kept out of paw’s reach.

Quick Scoop

  • Kalanchoe is a succulent that contains bufadienolides , a type of cardiac toxin that can affect a cat’s heart and digestive system if eaten.
  • Most household exposures cause mild to moderate symptoms like vomiting and diarrhea, but larger amounts can lead to serious heart and breathing problems.
  • Official pet poison plant lists classify kalanchoe as toxic to cats, so it is not considered a safe houseplant for cat households.

What Can Happen If a Cat Eats Kalanchoe?

  • Common, early signs:
    • Vomiting and diarrhea.
* Drooling, loss of appetite, and pawing at the mouth.
  • More severe, less common signs:
    • Lethargy, weakness, or collapse.
* Irregular heartbeat, tremors, seizures, or difficulty breathing in serious poisonings.

What To Do If Your Cat Nibbled Some

  1. Remove access
    • Take your cat away from the plant and remove fallen leaves or flowers so there is nothing else to chew on.
  1. Call a vet or poison service
    • Contact your veterinarian or a pet poison hotline right away, even if your cat only took a few bites, and follow their instructions.
  1. Watch for symptoms
    • Monitor for vomiting, diarrhea, drooling, lethargy, or any change in breathing or behavior, and seek emergency care if these appear or worsen.

Safer Plant Choices

  • If you love houseplants and live with cats, consider swapping kalanchoe for non‑toxic options listed on cat‑safe plant guides from veterinary and animal‑welfare organizations.
