Is southern lady fern safe for cats and dogs?
Use caution. Southern Lady Fern is on the mildly-toxic side of the ASPCA list. Most ingestions are short-lived but unpleasant for the pet; the cost-free fix is a placement they can't 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. Athyrium asplenioides is not listed in the ASPCA toxic or non-toxic plant database; out of caution, treat as mildly toxic to cats and dogs until authoritative confirmation of non-toxic status is available — possible symptoms from ingestion may include mild gastrointestinal upset.
