Is hay-scented fern safe for cats and dogs?
Not entirely — hay-scented fern is mildly toxic to cats and dogs. It rarely causes serious harm, but chewing it triggers real discomfort, so keep it out of a pet's reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. Dennstaedtia punctilobula is not individually listed by the ASPCA. Although most true ferns are non-toxic, this species is not specifically confirmed; treat it as uncertain, keep it away from pets, and verify with a vet rather than assuming it is safe.
