Plants Toxic to Cats and Dogs

Pick the plant. Each page states what the ASPCA Animal Poison Control list (and, where used, the Merck Veterinary Manual) says, quotes the source, and tells you what to do if a pet has eaten it. Confirm the species first; look-alikes are common.

This page reports what veterinary poison-control references say about each plant. It is not a promise that a plant is harmless, and it is not treatment advice. If a pet may have eaten a plant, contact a veterinarian, ASPCA Animal Poison Control (888) 426-4435 or Pet Poison Helpline (855) 764-7661.

How to use this list

Confirm the plant with a photo of the whole plant and a leaf close-up; names are reused across unrelated species.
Toxic means the reference expects poisoning; the signs listed are what the reference reports, not a diagnosis.
Non-toxic means no poisoning is expected; large amounts of any plant can still upset a stomach.
Not listed means we could not find the species in the references we opened; treat it as unknown.

FAQ

Which common houseplants are the most dangerous to cats?

True lilies (Lilium and Hemerocallis) are the ones veterinary references single out for cats: even pollen or water from the vase can cause acute kidney failure. Sago palm, oleander, foxglove and yew are serious for both cats and dogs.

Is a plant on the non-toxic list completely safe?

It means poisoning is not expected. Chewing a lot of any plant can still cause vomiting, and fertilizer or pesticide on the leaves is a separate risk.

Who do I call?

If a pet may have eaten a plant, contact a veterinarian, ASPCA Animal Poison Control (888) 426-4435 or Pet Poison Helpline (855) 764-7661.
