Plants add the needed finishing touches to any decor. But, if you have a feline, that beautiful plant could become a deadly enemy. Listed here are plants poisonous to cats that must be avoided if there are cats in your home. Note that lilies, in particular, are dangerous to cats. While in some cases, just parts of a plant (bark, leaves, seeds, berries, roots, tubers, spouts, green shells) might be poisonous, this list rules out the whole plant. If you must have any of them, keep them safely out of reach. Should your feline friend eat part of a poisonous plant, rush the cat to your veterinarian as soon as possible. If you can, take the plant with you for ease of identification.
