Boston ferns have exported to other parts of the world as decorative indoor plants thanks to their ability to thrive indoors with little care. They are a safe, non-toxic plant that makes them popular for pet owners.

These plants are great to hang in baskets on the porch or walkway. However, they do require some frequent misting for humidity.

What To Do If My Cat Eats a Boston Fern?

If you happen to find your cat eating or spitting out Boston fern leaves, don’t panic because like mentioned above, they are generally safe plants. If your cat ate a decent portion of the plant, it can cause some stomach irritation but the real damage is usually done to the plant instead of the cat.

I simple trick to keep your cat from getting into your plants is by simply adding vinegar to the water you spray with. This will make the Boston fern undesirable to your curious cat.

Treatment for Fern Poisoning in Cats

If your cat does happen to eat a fern that is poisonous, then it is advised that you take your cat to your local veterinarian office for further evaluation and treatment. Usually, treatment involves a medication to induce vomiting which will help remove the plant that is in the stomach to prevent future poisoning.

Next, they will give activated charcoal which helps absorb any leftover fern in the system. Last will be some IV fluids which will keep your cat hydrated and flush their system of the toxins.

If your cat starts to have sudden vomiting, drooling, and pain after eating a plant, it is very possible that your cat could have plant poisoning. You need to call the Pet Poison Hotline or get your cat to the veterinarians’ office.
