A favorite of interior designers and modern restaurants, the delicious monster is one of the most beloved and kept indoor or outdoor plants.

  • Learn the botanical name as well as common names of plants, as some mostly go by the same common name.

  • Keep contact information for your regular veterinarian and local emergency vet clinic handy in case of emergency.

  • Where possible, take a picture or bring a sample of the suspected poisonous plant to your veterinarian for positive identification. This will help with the medical consultation and prescribing the correct treatment.
