Is Dryopteris ludoviciana toxic to cats?

No — dryopteris ludoviciana 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. Not individually listed by the ASPCA, but it is a true wood fern (Dryopteridaceae), the same family as the ASPCA-listed non-toxic Boston and Christmas dagger ferns, and the ASPCA notes most true ferns are non-toxic to cats and dogs. Treat as low-risk, discourage heavy nibbling, and check with a vet if a large quantity is consumed.

Yes — the ASPCA lists dryopteris ludoviciana 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: Dryopteris ludoviciana is non-toxic to dogs as well. See the full dryopteris ludoviciana pet-safety guide for both species.
