Toxic Plants Checker for Cats & Dogs

True lilies and daylilies are an emergency for cats, and sago palm, oleander, and lily of the valley are dangerous to both cats and dogs. Many common houseplants, like pothos, philodendron, and monstera, cause painful mouth irritation, while spider plants, Boston ferns, calatheas, and parlor palms are pet-safe.

Other “lilies” (not kidney toxins)

Lily of the valley is not a true lily but is an emergency for cats and dogs because it affects the heart.

Toxic plants for pets: FAQ

Are lilies toxic to cats?

Yes. True lilies (Lilium, such as Easter, tiger, Asiatic, stargazer, and Oriental lilies) and daylilies (Hemerocallis) can cause sudden kidney failure in cats. Any part, even pollen or vase water, is dangerous, so call a vet right away even if your cat seems fine. Peace lilies and calla lilies are not true lilies: they irritate the mouth but do not cause kidney failure.

What house plants are safe for cats?

Houseplants the ASPCA lists as non-toxic to cats and dogs include spider plant, Boston fern, calathea and prayer plant, parlor, areca, and kentia palms, ponytail palm, African violet, peperomia, haworthia, moth orchids, cast iron plant, money tree, and hoya. Avoid lilies, pothos, philodendron, monstera, snake plant, aloe, and jade.

What plants are toxic to dogs?

The most dangerous plants for dogs include sago palm, oleander, foxglove, lily of the valley, yew, autumn crocus, and castor bean. Many common plants, such as tulip and daffodil bulbs, azaleas, pothos, philodendron, dieffenbachia, English ivy, aloe, and jade, cause drooling, mouth pain, vomiting, or diarrhea.

Is a sago palm poisonous to dogs?

Yes. Every part of the sago palm contains cycasin, and the seeds are the most toxic; one or two can be fatal. Signs include vomiting, diarrhea, weakness, seizures, and liver failure that can show 2-3 days later. Treat any sago palm ingestion as an emergency and call your vet or a pet poison hotline right away.

What should I do if my cat or dog ate a toxic plant?

Remove any plant pieces from your pet's mouth, keep a sample or photo of the plant, and call your vet, an emergency vet, the ASPCA Animal Poison Control Center at (888) 426-4435, or Pet Poison Helpline at (855) 764-7661 (a fee may apply). Do not induce vomiting unless a vet tells you to. For lilies and cats, sago palm, oleander, or lily of the valley, get help now even if your pet seems fine.

Verdicts are intentionally conservative: a plant is only marked non-toxic when the ASPCA lists it as non-toxic for that species. Plants we could not verify are not included.
