Bunnies, or rabbits, are strictly herbivorous and should not be fed fruit. Their diet should consist primarily of hay, with some fresh greens and vegetables added for variety and nutrition. Fruits contain high levels of sugar, which can be harmful to rabbits' digestive systems and lead to complications like diarrhea. Additionally, fruit is low in fiber and does not provide the necessary roughage that rabbits require for proper digestion and gut health. Stick to a diet of high-quality hay and appropriate greens for your bunny to ensure their well-being.
