If your pet ate a plant
Call your veterinarian, the ASPCA Animal Poison Control Center (888-426-4435), or Pet Poison Helpline (855-764-7661); a consultation fee may apply. For a child, call Poison Control at 1-800-222-1222. If a cat chewed any part of a lily, even pollen or vase water, treat it as an emergency.
How to Identify Are Poinsettias Poisonous?
Check these features before you rely on any single one — the combination is what confirms the ID.
The milky sap can irritate the mouth and stomach, causing drooling, licking, or vomiting in cats and dogs. Serious poisoning is very unlikely, and a child would have to eat an enormous amount to be harmed. Keep it out of reach, but don't panic.
True lilies (Lilium) and daylilies, common in holiday bouquets, can cause kidney failure in cats from a single bite, a little pollen, or a sip of the vase water. They're the most dangerous holiday flower for cat owners.
Both contain lycorine, which causes vomiting, drooling, and diarrhea. The bulbs are the most toxic part, and a dog digging up and chewing a bulb can become seriously ill.
Mistletoe berries and leaves can cause vomiting and diarrhea, and large amounts of European mistletoe can affect heart rate. Holly berries and spiny leaves cause vomiting and mouth injuries. Use artificial sprigs if you have pets or toddlers.
Pine, fir, and spruce needles and oils can upset the stomach, and needles can injure paws and mouths. Stagnant tree water with fertilizers or preservatives can make pets sick, and tinsel can cause dangerous intestinal blockages in cats.
Christmas, Thanksgiving, and Easter cactus, African violets, orchids, rosemary trees, and spider plants are considered non-toxic to cats and dogs, though eating any plant can cause mild stomach upset.
Holiday Plants Ranked by Risk to Pets
Lilies (Lilium & Daylilies)
Six-petaled trumpet flowers with prominent stamens, often in holiday bouquets. Potentially fatal kidney failure in cats from tiny exposures. Keep them out of homes with cats entirely.
Amaryllis
Huge trumpet-shaped red, white, or striped flowers on a tall bare stalk growing from a large bulb. Vomiting, drooling, and tremors in larger amounts; the bulb is the most toxic part.
Mistletoe
Evergreen sprigs with paired leathery leaves and small white berries. Vomiting and diarrhea; large amounts may cause heart and breathing problems.
Holly
Glossy, spiny-edged leaves with bright red berries. Causes vomiting, diarrhea, and drooling; spines can injure the mouth.
Paperwhites (Narcissus)
Clusters of small, fragrant white flowers grown from bulbs in pebbles or water. Vomiting and diarrhea; bulbs are sometimes mistaken for onions.
Poinsettia
Red, pink, or white leafy bracts around tiny yellow flowers. Mild mouth and stomach irritation only; far less dangerous than its reputation.
Christmas Cactus
Flat, segmented green stems with pink, red, or white tubular flowers at the tips. Non-toxic to cats and dogs, though chewing may cause mild upset.
