The Sago Palm is a very poisonous plant that is a common ornamental in Southern California. If a pet ingests even a small amount, especially of the seeds, it can be fatal! The Sago Palm has toxins in it which cause the pet to go into liver failure. Even with aggressive supportive care, there is a 30% mortality rate from Sago Palm ingestion. If you have these plants in your yard, please take pains to keep your pets away from them!
