The ASPCA Animal Poison Control Center (APCC) is your best resource for any animal poison-related emergency, 24 hours a day, 365 days a year. If you think your pet may have ingested a potentially poisonous substance, call (888) 426-4435. A $65 consultation fee may be applied to your credit card.
The ASPCA has compiled a list of plants which are either toxic or non-toxic to cats, dogs and horses. They also have convenient lists with botanical and common names as well as pictures to help you identify the plants. Please note that the information contained in the plant lists is not meant to be all-inclusive, but rather a compilation of the most frequently encountered plants.
