The ingestion of just one or two seeds can result in very serious effects, which include vomiting, diarrhea, depression, seizures and liver failure.

Lilies (Lilium spp.)

Members of the(Lilium spp.)are considered to be highly toxic to cats. While the poisonous component has not yet been identified, it is clear that with even ingestions of very small amounts of the plant, severe kidney damage could result.

Marijuana(Cannabis sativa)

Ingestion of(Cannabis sativa) by companion animals can result in depression of the central nervous system and incoordination, as well as vomiting, diarrhea, drooling, increased heart rate, and even seizures and coma.

Tulip/Narcissus bulbs(Tulipa/Narcissus spp.)

The bulb portions of (Tulipa/Narcissus spp.)contain toxins that can cause intense gastrointestinal irritation, drooling, loss of appetite, depression of the central nervous system, convulsions and cardiac abnormalities.

Azalea/Rhododendron (Rhododenron spp.)

Members of the(Rhododenron spp.)contain substances known as grayantoxins, which can produce vomiting, drooling, diarrhea, weakness and depression of the central nervous system in animals. Severe azalea poisoning could ultimately lead to coma and death from cardiovascular collapse.

Yew (Taxus spp.)

The Taxus spp.contains a toxic component known as taxine, which causes central nervous system effects such as trembling, incoordination, and difficulty breathing. It can also cause significant gastrointestinal irritation and cardiac failure, which can result in death. Most parts of the tree are toxic, except the bright red aril

Chrysanthemum (Compositae)

These popular blooms are part of the (Compositae) family, which contain pyrethrins that may produce gastrointestinal upset, including drooling, vomiting and diarrhea, if eaten. In certain cases, depression and loss of coordination may also develop if enough of any part of the plant is consumed. The leaves of the plant are toxic.

Pothos (Scindapsus and Epipremnum)

Pothos (both Scindapsus and Epipremnum) belongs to the Araceae family. If chewed or ingested, this popular household plant can cause significant mechanical irritation and swelling of the oral tissues and other parts of the gastrointestinal tract. All parts of the plant are toxic.

Poinsetta Plant (Euphorbia pulcherrima)

The milky white sap found in poinsettias contains chemicals called diterpenoid euphorbol esters and saponin-like detergents. While poinsettias are commonly “hyped” as poisonous plants, they rarely are, and the poisoning is greatly exaggerated. Mild signs of vomiting, drooling, or rarely, diarrhea may be seen. If the milky sap is exposed to skin, dermal irritation (including redness, swelling, and itchiness) may develop. Rarely, eye exposure can result in a mild conjunctivitis (“pink eye” secondary to inflammation). Signs are self-limiting and generally don’t require medical treatment unless severe. There is no antidote for poinsettia poisoning. That said, due to the low level of toxicity seen with poinsettia ingestion, medical treatment is rarely necessary unless clinical signs are severe.
