Poisonous plants to cats, Most complete list

Updated on March 24, 2013

As you already should know, cats musn't be allowed to eat plants, only cat grass as most plants are hazourdous to them.

The following list contains some of the plants that have been acknowledged as having systemic effects on cats and/or intense effects on the gastrointestinal tract.

Note that this list is not 100% complete and rather a compilation of the most frequently encountered plants. If you have reasons to suspect that your animal is ill or may have ingested a poisonous plant or substance, contact your local veterinarian and attend to a hospital, remember time in this situation is crucial.


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.
