Is Peacock fern toxic to cats?

No — peacock fern 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. Selaginella uncinata is not individually listed by the ASPCA, but its genus is clean: the ASPCA lists the closely related Selaginella kraussiana (Krauss' spikemoss / club moss) as non-toxic to cats, dogs and horses, and no Selaginella species appears on its toxic list. It is therefore treated as pet-safe — but verify with your vet before relying on this, especially if a pet is a persistent chewer.

Yes — the ASPCA lists peacock fern 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: Peacock fern is non-toxic to dogs as well. See the full peacock fern pet-safety guide for both species.
