How to read the results

Each plant gets a separate verdict for cats and for dogs, because some plants (like lilies) are deadly to one and mild for the other.

Emergency
Toxic and can be life-threatening. Go to a vet right away, even before symptoms.
Toxic
Can make a pet quite ill. Call your vet or a poison helpline.
Mildly toxic
On the ASPCA toxic list; usually causes mouth or stomach upset.
Treat as toxic
Not on the ASPCA list, but contains known irritants. Keep out of reach.
Non-toxic
On the ASPCA non-toxic list. A big nibble may still upset a tummy.
Likely safe
Not on the ASPCA list, and no poisonings are reported.

Quick answers

Which houseplants are safe for cats and dogs?
Which common houseplants are toxic to cats and dogs?
Which plants are the most dangerous for pets?

These plants can cause organ damage or death. If your pet eats any part of one, go to a vet immediately:

True lilies and daylilies are emergencies for cats only; the ASPCA lists them as non-toxic to dogs.

Are lilies toxic to cats? What about dogs?

Yes. True lilies (Lilium: Easter, tiger, Asiatic, Stargazer and Oriental lilies) and daylilies (Hemerocallis) can cause fatal kidney failure in cats. Licking pollen off their fur or drinking water from the vase is enough. Signs start with vomiting, drooling and hiding, then kidney failure within 1 to 3 days. Go to a vet straight away; treatment within about 6 hours gives the best chance.

The ASPCA lists these lilies as non-toxic to dogs, though they can still upset a dog’s stomach. Peace lilies, calla lilies and Peruvian lilies are not true lilies: peace and calla lilies irritate the mouth, and Peruvian lilies (Alstroemeria) are non-toxic.

Which flowers are safe in a bouquet if I have a cat?
Are herbs safe for cats and dogs?

These herbs are listed as non-toxic to both:

These are toxic or best kept out of reach; most cause stomach upset, but onion, garlic, chives and leeks can damage red blood cells:

What does “Not on the ASPCA list” mean?

The ASPCA list is the most widely used reference, but it does not include every plant. When a plant isn’t on it, we say so plainly and show what is known: either Treat as toxic (it contains the same irritants as listed relatives, or vets report poisonings) or Likely safe (no poisonings reported). We never mark an unlisted plant as “non-toxic”.

How do you decide the risk level?

Whether a plant is toxic comes from the ASPCA lists for cats and dogs, checked in November 2026. The ASPCA does not grade severity, so our risk level (mild, toxic, emergency) is a plain-English summary of the type of toxin and the effects described in veterinary references. It is a guide, not a diagnosis: always follow your vet’s advice.
