Picking plants in the wild, and bringing them home for your rabbit to eat, can be a wonderful thing. It’s fun and rewarding for you, and makes a varied and wonderful addition to your rabbit’s diet. However, there are some plants that can be harmful, and even fatal if consumed.

This list includes plants that are toxic in one way or another. Just because a plant is not listed here does not mean it can’t be toxic. Please don’t feed your rabbit plants you are not absolutely sure are safe. Don’t trust your rabbit to decide for itself which plants are harmful. In this list, plants marked in red are considered highly toxic and may be fatal. Other plants can be mildly toxic and may cause local irritations of the skin and mucus membranes, or affect the digestive tract or nervous system. The list also includes a few common garden and indoor plants.
