My cat ate Giant Water Lily — what to do
Step by step
- Take giant water lily away and remove any plant material from your cat's mouth so they cannot eat more.
- Note roughly how much was eaten and when — this helps the vet judge the risk.
- Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
- Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
- 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 giant water lily — FAQ
Is giant water lily poisonous to cats?
Yes — the ASPCA lists Giant Water Lily (Nymphaea gigantea) as mildly toxic to cats. Nymphaea gigantea is not specifically listed by the ASPCA; however, some Nymphaea species contain alkaloids (nupharamine alkaloids) in rhizomes that may cause gastrointestinal upset if ingested in quantity. Classified as mildly-toxic as a precaution; not expected to cause serious harm in brief contact but keep pets from chewing rhizomes.
How serious is it if my cat ate giant water lily?
Giant 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 gigantea is not specifically listed by the ASPCA; however, some Nymphaea species contain alkaloids (nupharamine alkaloids) in rhizomes that may cause gastrointestinal upset if ingested in quantity. Classified as mildly-toxic as a precaution; not expected to cause serious harm in brief contact but keep pets from chewing rhizomes. 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?
