Is Bleeding Heart toxic to cats?

Dicentra spectabilis

Toxic to cats

Yes — bleeding heart is toxic to cats according to the ASPCA. Keep it well away from any cat that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List. All parts of Dicentra spectabilis are toxic to cats and dogs (and mildly toxic to humans). The plant contains isoquinoline alkaloids — specifically protopine, allocryptopine, and related compounds — which act as GABA antagonists. Ingestion can cause trembling, staggering, vomiting, diarrhoea, laboured breathing, and in larger doses, seizures. Toxicity risk is higher in small-breed dogs and cats. The Pet Poison Helpline lists Bleeding Heart as toxic to both cats and dogs. Keep away from pets and wash hands after handling.

What to do if your cat ate bleeding heart

  1. Remove any plant material from your cat's mouth and move bleeding heart out of reach.
  2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
  3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
  5. Bring a leaf or photo of bleeding heart to the appointment so it can be treated correctly.
