Symptoms will vary from animal to animal. Some may eat these plants and will exhibit no symptoms; others will exhibit local irritants, such as drooling, vomiting, diarrhea, irritation to the mouth and skin or swelling of area around the mouth. Extreme cases of poisoning may cause convulsions, tremors to the heart, respiratory and kidney problems, and, in the most extreme cases, may cause coma and death. It is good to note that most dogs and cats will vomit after chewing on plants. This probably does not mean poisoning. Only persistent or severe vomiting is a danger sign, especially when accompanied with one or more of the other symptoms.

Be sure to know the names of all the plants in and around your home and keep potentially toxic plants out of the areas accessible to your pet. If your pet should happen to be poisoned by a hazardous plant or any other substance, contact your veterinarian immediately. Do not try to induce vomiting without consulting a veterinarian first. Always be sure to keep the phone number of your vet and the Animal Poison Control Center near your phone.
