Is White Water Lilytoxic to cats & dogs?

Is white water lily safe for cats and dogs?

Not entirely — white water lily is mildly toxic to cats and dogs. It rarely causes serious harm, but chewing it triggers real discomfort, so keep it out of a pet's reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. Nymphaea alba is not individually listed on the ASPCA toxic or non-toxic plant database. The ASPCA's dangerous 'lily' listings refer specifically to Lilium and Hemerocallis, which are botanically unrelated to true waterlilies. However, anecdotal veterinary reports document GI upset — vomiting, drooling, and lethargy — in pets that have chewed waterlily foliage. As ASPCA status is unconfirmed and some irritant compounds (including tannins and alkaloids) have been reported in Nymphaea, treat with caution rather than as confirmed pet-safe. Verify with a vet if ingestion occurs; contact ASPCA Animal Poison Control (888-426-4435) for guidance.

If you see drooling, pawing at the mouth, head-shaking, vomiting, loss of appetite, or unusual lethargy after your pet has had access to white water lily, treat it as a suspected ingestion and act on the steps below.

What to do if your pet ate white water lily

1. Remove any plant material from your pet's mouth and move white water lily out of reach.
2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
5. Bring a leaf or photo of white water lily to the appointment so it can be treated correctly.

This page is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide rather than the plant. If you are worried, always contact a vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
