Poisonous Plants

Ingestion of even small amounts of certain plants can be harmful or fatal to a pet.

Symptoms of Plant Poisoning

Symptoms of plant poisoning include:

  • Irritation to skin and/or mouth
  • Drooling
  • Diarrhea
  • Seizures
  • Lethargy
  • Unconsciousness
  • Vomiting. Please note that vomiting is common after a cat or dog ingests plant material. Seek veterinary care if vomiting accompanies other symptoms or if you suspect that your pet has ingested any toxic substance. Time is of the essence in treatment.
