Plants Which Are Potentially Poisonous for Cats
Veterinary & Aquatic Services Department, Drs. Foster & Smith

Cats and kittens will often chew on grasses and other plants. Unfortunately, many plants are dangerous. Some may cause vomiting or diarrhea while others may cause organ failure and death. Pet owners should take the responsibility of keeping pets away from dangerous plants.

Below, we have provided a list of some of the more common poisonous plants. This is not an all-inclusive list. The same plant may also have different common names depending on the area of the country in which one resides. Every pet owner should know what plants are in and around his/her house.

If you think your pet has chewed on or eaten one of these plants, please contact your veterinarian, animal emergency clinic, or the poison control center for advice. The ASPCA National Animal Poison Control Center hotline number is as follows:

  • 1-888-4ANI-HELP or 1-888-426-4435 ($65.00 per case). The charge is billed to caller's credit card.
