What to Do if Your Pet Eats a Poisonous Plant

If your cat ingests a poisonous plant, your first step should be to phone your veterinarian, the ASPCA National Animal Poison Control Center, or the Pet Poison Helpline for advice. Be prepared to give the proper name of the plant, along with how much they ate. It's also a good idea to keep a feline first aid kit on hand for emergencies.

If you call the poison control center and tell them what your cat’s nibbled on, they will tell you what kind of first response treatment to give your cat, if needed. Some plants are so toxic to cats that they can be fatal or cause severe damage to a cat's internal organs, such as the kidneys, so it's always better to err on the side of caution and reach out for advice.
