If you have an adult bunny remember that need fruits and vegetables daily. Their diet should consist of 80% Timothy Hay, 10% pellets (please choose a good brand that is not too sugary, I use timothy based ones for my bunny) and 10% fruits and vegetables. Vegetables such as broccoli, brussel sprouts, cabbage, cauliflower, and kale are a good idea. Avoid giving them carrots as it is too sugary and should only be given as a treat. My bunny likes cilantro and mint, so I try and include that in a mix of spinach.
