Poinsettias, gorgeous plants with vibrant red flowers is the perfect plant for your holiday decor, but they're not totally innocent. The stems of the plant are filled with a milky white sap, which contains chemicals that can irritate cats’ and dogs’ digestive systems, according to the U.S. Food and Drug Administration.

To be clear, poinsettias are only mildly toxic, and you don’t need to rush Fluffy to the vet if you catch her nibbling on that crimson foliage. But knowing the risk of poinsettia sap — and making sure your pet can’t reach the holiday plant — could save your pet from an evening of unpleasant symptoms. Since your pet makes you a little healthier, don’t you want to return the favor?
