Is Boston fern toxic to cats and dogs?
Quick answer
Good news: Boston fern is listed as non-toxic to cats and dogs by the ASPCA. You can keep it in a home with pets without worrying about accidental nibbling causing serious harm.

Boston fern is safe, but asparagus fern is not a true fern and ASPCA lists it as toxic: its berries can upset the stomach, and repeated skin contact can cause allergic dermatitis.
Why it’s safe
The verdict comes from one place: the ASPCA’s list of non-toxic plants, checked by hand against this species rather than inferred from its family. The list is about poisoning, which is not the whole of what a plant can do to a pet. A cat or dog that eats a lot of any plant can still get an upset stomach.
Keep it out of reach not because it’s dangerous, but because soil and leaves can tempt curious pets who might dig or knock the pot over.
