Is Wild Senna toxic to cats?

Senna hebecarpa

Mildly toxic to cats

Mildly. The ASPCA lists wild senna as mildly toxic to cats — a chewing cat typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Leaves and seeds contain anthraquinone glycosides (sennosides), which act as potent stimulant laxatives. Ingestion can cause vomiting, diarrhea, abdominal cramping, and dehydration in cats and dogs; large quantities may lead to electrolyte imbalance. Not formally listed on the ASPCA toxic plant database but veterinary and toxicology sources consistently flag the genus Senna as a GI irritant and laxative hazard for pets.

What to do if your cat ate wild senna

  1. Remove any plant material from your cat's mouth and move wild senna 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 wild senna to the appointment so it can be treated correctly.

General guidance, not veterinary advice. If you think your cat has eaten wild senna, contact your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
