Cats chew on plants. It helps them deal with the swallowed hair in their stomach. 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.
