Symptoms of kalanchoe poisoning in cats

  • Vomiting
  • Diarrhea
  • Abnormal heart rhythm (rare, with large amounts)
  • Weakness

Why kalanchoe is toxic to cats

Cardiac glycosides work like an overdose of the heart drug digoxin. They block a pump that heart cells need to control their rhythm, which can cause a dangerously slow or irregular heartbeat, high blood potassium and sudden collapse. The toxin is present in every part of the plant and in water the plant has stood in.

What to do if your cat ate kalanchoe

  1. Remove plant pieces from your cat's mouth and move cats away from the plant. Wipe sap or pollen off the fur and paws with a damp cloth.
  2. Call your vet or animal poison control for advice: ASPCA Animal Poison Control: (888) 426-4435 · Pet Poison Helpline: (855) 764-7661.
  3. Identify the plant. Take a photo or bring a piece (or the plant label) to the vet, and estimate how much was eaten and when.
  4. Do not make your cat vomit unless a vet tells you to. Home remedies such as hydrogen peroxide or salt can cause serious harm, and hydrogen peroxide is not safe for cats.
  5. Watch for vomiting, diarrhea, abnormal heart rhythm. Do not wait for these signs before getting help.

Treatment and outlook

This is an emergency. Vets decontaminate (vomiting and activated charcoal, often repeated), give IV fluids, monitor the heart with an ECG, and treat arrhythmias. Digoxin-specific antibody fragments are used in severe cases.

How to keep your cat away from kalanchoe

  • Place kalanchoe on high shelves or in hanging planters away from furniture cats can climb, or in a room your cat cannot enter.
  • Give your cat something better to chew: a pot of cat grass or catnip often distracts cats from houseplants.
  • Pick up fallen leaves, petals and pollen promptly, and empty vases where pets can reach them.
