Common questions
Is button fern related to Boston fern in safety?
Yes — both are true ferns and both are non-toxic, along with maidenhair, rabbit’s foot and holly ferns.
My cat vomited a leaf ball after chewing the fern — dangerous?
That is ordinary fiber vomit, the same as a hairball. The plant contributed no toxin. If vomiting is repeated or the cat stops eating, look for a different cause.
