Cats will chew on plants. And, because they love to climb and explore, it is difficult to keep plants out of their reach. Therefore, if you are going to have plants in your house, or if you let your cat out in your yard, you need to be able to accurately identify the plants to which your cat will be exposed. When in doubt, however, it is best to remove the plant from your home.
If a plant is poisonous, assume all parts of the plant are poisonous -- though some parts of the plant may have higher concentrations of the toxic principle than others. Many toxic plants are irritants: they cause inflammation of the skin, mouth, stomach, etc. The toxic principle in other plants may only affect a particular organ like the kidney or heart.
The following is a listing of plants that are toxic to cats, as well as the most commonly encountered toxic plants:
- Amaryllis (Amaryllis sp.)
- Autumn Crocus (Colchicum autumnale)
