Lilies: the holiday flower that can kill a cat

Every part of a true lily (Lilium) is toxic to cats: leaf, stem, flower, pollen. It can cause acute kidney failure, and treatment has to start early. Vase water is thought to be toxic too. A cat that brushes past and licks pollen off its fur counts. If your cat touched a lily, call now, not after signs show.

Many lilies in holiday bouquets are highly toxic to cats. Ask the florist to leave them out, and check a gift bouquet at the door before it comes inside.

Amaryllis: toxic to cats, and the bulb is worse

Amaryllis is toxic to cats. Chewed flowers and leaves bring vomiting and diarrhea. The bulb is more toxic: eaten in a large amount, it can cause weakness, tremors, seizures and changes in blood pressure. Grow kits often sit on a low table. Put them on a shelf your cat can't reach, or swap for a Christmas cactus.

Mistletoe: toxic, so hang it out of jumping range

American mistletoe is toxic to cats, causing vomiting and diarrhea. It can also slow the heart and, rarely, drop blood pressure. A doorway sprig is in reach of a cat on a shelf or a door frame: hang it where nothing can jump to it, or use a fake sprig.

Christmas tree: needles and stand water are mild

Spruce and fir needles can irritate the mouth and stomach, with vomiting and drooling. A large amount can block the gut, because needles don't digest well. Tree water breeds bacteria that can cause nausea and diarrhea. Cover the stand so your cat can't drink from it, and sweep up needles daily.

Poinsettia and holly: mild, not an emergency

Poinsettia sap irritates the mouth and stomach and sometimes causes vomiting, but the plant is overrated in toxicity. What to watch for after a chew: are poinsettias poisonous to cats.

Holly causes vomiting, diarrhea, drooling and lethargy; the leaves and berries are low in toxicity. Sweep up fallen berries anyway.

Safe plants: Christmas cactus and a lily-free bouquet

Christmas cactus is non-toxic to cats. A big chew may still cause mild vomiting or diarrhea, but nothing serious is expected. It is the easiest swap for an amaryllis.

Want flowers on the table? Roses with the thorns off, sunflowers and gerbera daisies are all non-toxic to cats.

Cat chewed a holiday plant? What to do now

  • Take the plant away, and check the mouth for leftover pieces.
  • For any lily, call now, even if your cat seems fine. Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435, or Pet Poison Helpline at (855) 764-7661. Both answer 24/7, and a fee may apply.
  • Note what the plant was, which part, about how much and when. Keep the plant or its tag nearby.
  • Don't make your cat vomit unless a vet tells you to.
