Pet-safety information is a general guide from the ASPCA's toxic-plant database and covers cats and dogs only. "If eaten" summarises the symptoms ASPCA lists for that plant; how an animal actually reacts depends on how much it ate and on the animal. It isn't exhaustive, isn't veterinary advice, and individual animals vary — never rely on it as the sole basis for a decision about your pet. If you think your pet has eaten a harmful plant, contact a vet immediately.
