March 1, 2024

Spring is in full swing, which means many of us are enjoying the outdoors and appreciating our plants and flowers. While the backyard is typically a fun oasis for your four-legged friend, there are certain plant types that are harmful to animals. Take care to keep these toxic species away from your pets.

1. Lilies

Additional names: Daylily, Easter lily, Japanese show lily, Oriental lily, Rubrum lily, Stargazer lily, Tiger lily, Wood lily

Lilies are beautiful and popular spring flowers to plant in the garden and indoors, but most lilies are extremely toxic to your pets. Cats are particularly sensitive to the toxic effects of lilies,  as just a small amount can be fatal.

10. Castor bean plant

Additional names:  Castor Oil Plant, Mole Bean Plant, African Wonder Tree, Castor Bean

These beans are highly toxic to your pet due to the ricin found in the plant. The entire plant is toxic to animals, especially the beans, where ingestion of only a small amount can lead to devastating effects for your pet. Signs may include loss of appetite, excessive thirst, weakness, colic, trembling, sweating, loss of coordination, difficulty breathing, progressive central nervous system depression, and fever. If left untreated, bloody diarrhea may occur, and convulsions and coma can precede death.

The list above are just some of the plants that can be harmful to your pet but there are more.

If you have a dog or cat who likes to eat your plants, it is best not to leave them unsupervised around these items and be sure not to leave yard trimmings they could access.

Should you suspect your pet has ingested something toxic, call your veterinarian or an emergency veterinary clinic immediately. How quickly treatment is started can mean the difference between life and death.
