Are Peace Lilies Toxic to Cats and Dogs? What to Do Next

Are peace lilies toxic to cats and dogs? ASPCA lists Peace Lily, Spathiphyllum, as toxic to both. If a pet may have chewed the plant, the useful first decision is not to judge the bite at home. Keep the plant label or take a clear photo, note what may have happened, and call a veterinarian or animal poison-control service before trying a remedy.

Start With the Plant Name, Not the Word “Lily”

“Lily” is a common name, not a complete safety answer. ASPCA identifies Peace Lily as Spathiphyllum, a houseplant with large green leaves and a distinctive flower. That is different from true Lilium and daylily plants, which have their own risk profile—especially for cats.

The practical task is to preserve information, not to make a botanical diagnosis from one internet photo. If the pot, plant tag, store receipt, or bouquet label is available, keep it. A photo that shows the whole plant and label can also help the professional you call. Added fertilizer, plant food, pesticides, mixed arrangements, and an uncertain identity can change the conversation.

What ASPCA Lists for Peace Lily Exposure

The ASPCA Animal Poison Control Center record lists Peace Lily as toxic to cats and dogs and names insoluble calcium oxalate crystals as its toxic principle. It describes oral irritation or burning, drooling, vomiting, and difficulty swallowing among possible clinical signs after chewing.

Those observations are useful details for the call; they are not a severity score. A pet who looks normal has not supplied a safe-at-home verdict, and a pet who drools or vomits has not supplied a diagnosis. Peace Lily also should not be treated as interchangeable with every other plant called lily. The plant’s scientific name keeps the risk discussion attached to the right reference.

Make the First Call Useful

The American Veterinary Medical Association’s pet-first-aid guidance puts the priority on professional direction before vomiting or medication is attempted. When you call, share the pet’s species, approximate age and weight, current changes you have noticed, the plant name or photo, when the access may have happened, and what part or amount may be involved if you know it. Keep the container or label nearby.

Do not make the pet vomit, give milk, food, medication, or another home remedy unless the veterinarian or poison-control service specifically directs it. The right next step may depend on details that are impossible to settle from a short symptom list or an uncertain plant name.

Use a Calm Houseplant Check Before Access Happens

If you are bringing home a Peace Lily, treat the label as a safety detail rather than decoration. Confirm the botanical name, consider who can reach the plant as they climb, jump, or explore, and avoid relying on a single “out of reach” spot as a permanent solution. A new cat or dog may use rooms differently once they settle in.

If the plant is already in the home, a useful prevention note has four parts: the name on the label, the room, the route a pet could use to reach it, and the professional number you would call. That note does not predict whether a pet will chew a leaf. It simply makes a possible exposure easier to describe promptly.

The Bottom Line for Peace Lily and Pets

Peace Lily is not a harmless name variation, and it is not the same thing as every true lily. ASPCA lists Spathiphyllum as toxic to cats and dogs. When exposure is possible, preserve the plant information, call a veterinarian or animal poison-control service promptly, and let them advise the next step instead of experimenting at home.
