No action needed. Hang it out of batting range for the fronds' sake, not the cat's.

FAQ
My cat treats the Boston fern like a toy and chews the fronds — is that a problem?
Not for the cat. The ASPCA lists the Boston fern (Nephrolepis exaltata bostoniensis) as "Non-Toxic to Cats" and non-toxic to dogs — there is no toxin on record, which is why it anchors our fern family guide's safe side. The dangling fronds are irresistible to batters and chewers, so the plant will show damage long before your cat shows any. One check first: make sure it really is a Boston fern — the look-alike 'asparagus fern' is a different, toxic plant. Ours has soft spore-bearing fronds and never berries; see the fern guide for the split.
