Common questions
Are all true ferns safe for cats?
No. Bird’s nest, Boston and maidenhair ferns are safe, but asparagus fern is not a true fern and is toxic. Always check the species.
The spore dots on the underside — are they harmful?
No. Those are the fern’s spores (sori), a normal part of reproduction and harmless if a cat licks or chews a frond.
