here are many common foods, plants and weeds that are poisonous to rabbits and it is helpful to identify some of these.
While we discuss here, the foods, plants or weeds to avoid, it is by no means a comprehensive list and anything not mentioned here does not mean it is not harmful to your rabbit.
Rabbits are vegetarians but they cannot eat any vegetable, plant or weed.
There are foods that are safe for humans and other animals, but will have a harmful effect on a rabbit.
Some of these foods, vegetables, plants or weeds are harmful in varying degrees, while others will result in killing a rabbit.
It is far better to identify and know the foods and plants/weeds that are safe for your rabbit to eat and then exclude every other single plant or type of food.
