My cat ate White Water Lily — what to do

Step by step

  1. Take white water lily away and remove any plant material from your cat's mouth so they cannot eat more.
  2. Note roughly how much was eaten and when — this helps the vet judge the risk.
  3. Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
  5. Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.

This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435.

My cat ate white water lily — FAQ

Is white water lily poisonous to cats?

Yes — the ASPCA lists White Water Lily (Nymphaea alba) as mildly toxic to cats. 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.

How serious is it if my cat ate white water lily?

White Water Lily is mildly toxic, so most cats get short-lived mouth irritation, drooling, and vomiting rather than a life-threatening reaction. It is still worth a vet call to be safe, especially if your cat ate a lot or symptoms persist.

What symptoms should I watch for?

Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. 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.

Verify with a vet if ingestion occurs; contact ASPCA Animal Poison Control (888-426-4435) for guidance. Any worsening or persistent symptoms warrant an immediate vet visit.

Should I make my cat vomit?

No — do not induce vomiting unless a vet or the ASPCA Animal Poison Control Center specifically tells you to. The wrong action can make things worse. Call (888) 426-4435 and follow professional advice.

How do I stop this happening again?

Keep white water lily well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
