True fern plants are non-toxic to cats.
Belonging to the class Polypodiopsida, ferns are plants that reproduce via spores. They are unique as they do not have seeds and flowers. Moreover, ferns go beyond just being ornamental houseplants with beautiful fronds. Some are used for medicine, food, or even biofertilizer.
The American Society for the Prevention of Cruelty to Animals (ASPCA) lists true fern species that are non-toxic to cats. These include bird’s nest fern, Boston fern, button fern, carrot fern, fishtail fern, maidenhair fern, mother fern, rabbit’s foot fern, staghorn fern, and sword fern.
However, it’s important to know that some plants with fern in their name are poisonous to cats. Asparagus fern, California fern, and fern palm are some examples. From saponins to alkaloids, different toxic compounds found in these plants may harm your pet.
What to do if your cat accidentally comes into contact with, chews, or eats fern plants: As a cat owner, you are responsible for keeping your cat safe. This includes bringing home non-poisonous plants into your home.
In case your cat accidentally comes across a toxic fern plant, call your veterinarian immediately. Take the fern away and observe her in a confined space over the next 24 hours. Discard any plant material found on your cat’s hair, skin, or mouth.
More importantly, monitor her for symptoms of poisoning. The signs may vary depending on what kind of toxins and how much she was exposed to them. Salivation, vomiting, diarrhea, twitching and fitting, and difficulty in breathing may occur. She may also experience skin inflammation or swelling, depression or coma, shock or collapse, and changes in her drinking, urinating, and appetite.
If your cat’s condition worsens, take her to see the vet. Moreover, bring a sample of the plant to help determine its toxins.
In summary: Most true ferns are safe for cats. But if you’re uncertain about a particular fern plant, refrain from bringing it home to avoid accidents. Also, check out the lists of ASPCA, PetMD, and Pet Poison Helpline. They’ll help you determine which ones are toxic or safe for cats.
