Holiday Plants Toxic to Pets and Safer Swaps

Last updated November 15, 2026

Some holiday plants are toxic to pets. Lilies can be deadly to cats, while poinsettias mostly cause an upset stomach. See which plants to skip and safer swaps.

Key Takeaways

• Lilies can cause fatal kidney failure in cats, even from pollen or vase water.
• Poinsettias are mildly toxic and usually cause mouth and stomach irritation.
• Holly, amaryllis and mistletoe can make pets sick.
• Poison control lists Christmas cactus as non-toxic to cats and dogs.

Which Holiday Plants Are Toxic to Pets?

The most dangerous holiday plant for cats is the lily. Holly, amaryllis, mistletoe and poinsettia can also cause problems, but most are less severe.

Plants show up in bouquets, centerpieces and gifts this time of year. That makes it easy to bring a risky one home without thinking.

Holiday Plant Risk Ladder

We ranked common holiday plants from most to least risky, using poison control and federal guidance.

Poison control here means the American Society for the Prevention of Cruelty to Animals (ASPCA) Animal Poison Control Center.

Why Lilies Are So Dangerous for Cats

True lilies and daylilies are the problem. Every part is poisonous to cats, including the pollen and the water in the vase.

A cat may only lick pollen off its fur and still get very sick. Without fast treatment, kidney failure can follow within one to three days, says the US Food and Drug Administration.

Dogs usually get only a mild upset stomach from lilies. Still, keep them away to be safe.

The Truth About Poinsettias

Poinsettias have a scary reputation. Poison control says they are “generally over-rated in toxicity” for pets.

Their sap can irritate the mouth and stomach and sometimes cause vomiting, per the ASPCA poinsettia page.

So a nibble is rarely an emergency. Watch your pet and call your vet if they seem unwell. Our poinsettia care tips explain where to place the plant out of reach.

Safer Plant Swaps for Pet Homes

You can still decorate with living plants. These swaps lower the risk.

• Choose a Christmas cactus instead of lilies or amaryllis.
• Use fake holly and mistletoe, placed high up.
• Ask florists to leave lilies out of holiday bouquets.
• Keep any plant on a high shelf, away from jumping cats.

Tinsel, ribbon and ornaments can also block a pet’s intestines, the American Veterinary Medical Association warns. Our winter pet safety tips cover cold weather risks too.

When to Get Help

Call your vet or an emergency clinic right away if your pet ate a holiday plant and shows these signs. This list follows federal guidance.

• Vomiting or drooling
• Low energy or hiding
• Loss of appetite
• Peeing more, or signs of thirst and dehydration in cats

If your cat touched or ate any part of a lily, get help even if it seems fine. Bring the plant or a photo of it to the vet.

You can also call the ASPCA Animal Poison Control Center at 888-426-4435. A consultation fee may apply.
