Every animal must consume specific foods to maintain good health. Rabbits need nutritious food to live long and healthy. They are herbivores, which means they must consume plants like hay, fruits, and vegetables. But what foods can be toxic to rabbits?

There are also foods for rabbits that aren't toxic but need to be given in a limited amount. Some foods aren't poisonous to bunnies, but as much as possible, we must avoid these kinds because they're unhealthy.

Rabbits should be given unlimited hay and water daily. Other than hay, some plants should be given in a limited amount.

If you are a new rabbit owner, research this topic to ensure you are feeding your bunny the right foods that are healthy and beneficial. Healthy foods for rabbits provide specific nutrients that they need.

If you already know what is good for them, here is a list of food you should avoid because they are toxic to rabbits.

List of Toxic Foods to Rabbit

Fruit seeds in apples and plum pits contain cyanogenic glycosides, the natural toxins in plants.


Avocados have a fungicidal toxin called Persin which can cause heart failure in rabbits.

Iceberg lettuce

Some kinds of lettuce are suitable for rabbits, like Romaine and Butterhead. Iceberg lettuce is toxic to rabbits because it has lactucarium which is dangerous when given in large amounts. It is safer to give the other kinds of lettuce than the latter.

Chocolate contains theobromine and caffeine that can poison a bunny. Too much sweetness can be toxic to rabbits.
