Lena writes the safety side of Fern & Feline: which plants are safe for cats and dogs, which ones aren't, and what to do in the first 30 minutes if your pet ate something they shouldn't have. She started this work after her own cat chewed on a lily and the panicked 3am Google search produced six contradictory answers. She works with the ASPCA toxic-plants database, Pet Poison Helpline references, and peer-reviewed veterinary sources, and cites them in every article. She is not a veterinarian; for emergencies, always call your vet or Pet Poison Helpline (888-426-4435).
