Is Stiff-leaved Aponogeton toxic to cats?

No — stiff-leaved aponogeton 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. Aponogeton rigidifolius is not individually listed by ASPCA. The Aponogeton genus has no known toxic compounds in the botanical or veterinary literature, and this species is consistently described as fish- and invertebrate-safe in aquarium hobby sources. Consult a vet if a pet consumes large amounts.

Yes — the ASPCA lists stiff-leaved aponogeton 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: Stiff-leaved Aponogeton is non-toxic to dogs as well. See the full stiff-leaved aponogeton pet-safety guide for both species.
