Is leatherleaf fern safe for cats and dogs?
Not entirely — leatherleaf fern is mildly toxic to cats and dogs. It rarely causes serious harm, but chewing it triggers real discomfort, so keep it out of a pet's reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. Rumohra adiantiformis is not individually listed on the ASPCA Toxic and Non-Toxic Plants database, and the genus Rumohra is not covered, so it cannot be confirmed pet-safe. True ferns are generally low-risk, but treat with caution: discourage chewing and consult a vet if a pet ingests it, as effects in cats and dogs are not well characterised.
| Pet | Toxic? | Per ASPCA |
|---|---|---|
| Cats | Yes (mild) | Mildly toxic to pets |
| Dogs | Yes (mild) | Mildly toxic to pets |
