Is Crimson Water Lily toxic to cats?

No — crimson water lily is listed by the ASPCA as non-toxic to cats. It is a sensible choice for a home with a cat; a curious nibble will not poison them, though no plant is meant to be eaten. Nymphaea genus (water lilies) are generally regarded as non-toxic to dogs, cats and horses. 'Laydekeri Fulgens' shares this safety profile. Always confirm plant identity — true Lilium lilies and daylilies (Hemerocallis) are toxic and should not be confused with Nymphaea. ⚠️ The ASPCA does not list this species individually, so this reflects genus- and family-level inference rather than a direct listing — and our own records disagree across the genus. If your pet has eaten it, treat it as unverified and call your vet or the APCC on (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK rather than relying on this page.

Yes — the ASPCA lists crimson water lily as non-toxic to cats and dogs. A cat that chews a large amount of any foliage can still get a mild, brief stomach upset, so discourage grazing, but it will not be poisoned.

The ASPCA classification Growli uses applies to both cats and dogs: Crimson Water Lily is non-toxic to dogs as well. See the full crimson water lily pet-safety guide for both species.
