                                According to the ASPCA, *Portulaca oleracea*, also known as purslane, is toxic to dogs, cats, and horses due to its soluble calcium oxalate content. While this common weed is celebrated as a nutritious food source for humans, its safety varies dramatically depending on who is consuming it.
