What this means for your cat
Cats can live around a giant sword fern. The ASPCA lists Nephrolepis biserrata (Bold Sword Fern) as non-toxic to cats, with no identified toxic principle. A cat that nibbles a frond is not at risk of plant poisoning, though chewing tough fibrous foliage can occasionally trigger transient vomiting like any indigestible plant material.
