ASPCA Animal Poison Control Center. If your pet may have ingested something toxic like human or veterinary medicine, rat poison, chocolate, etc, you need to seek veterinary help. The ASPCA Animal Poison Control Center can tell you how to proceed. They are staffed by toxicologists 24 hours per day, year-round. You need to know your pet's approximate weight, when the toxin was ingested and in what amount. Please keep the packaging nearby so that the toxic dose for your pet can be calculated. ASPCA may charge your credit card $65 for the consultation which will guide any veterinary care and follow-up that is necessary.
