Listed here are plants poisonous or toxic 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 any part is toxic. If you must have any of them, keep them safely out of reach.

Toxic Plants Index, provides an extensive list of genus/species and common names of plants known to be toxic to small animals. After the index, each plant species is written up with a brief description of the known common names, the toxin or toxins produced by the plant, and the part or parts of the species that are known to be toxic. A paragraph describing clinical signs caused by the plant is followed by known treatment recommendations.

Should your cat 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.

If you do not see a particular plant on this list, the omission DOES NOT indicate the plant is not poisonious.  Always check with your veterinarian before bringing any plant into your home.
