From what is good for the rabbit is to have HAY access all day. They should have 75% of their diet HAY. I also leave a container of pellets for them to get to all day. There is i big controversy about what to feed them and what not to feed of veggies and greens. I believe that no ICE-BURG LETTUCE should be give at any time! Cabbage, beans,
parsnips, rhubarb are not good either.
Things that I see that they say not to give to rabbits others say they give this to their rabbit. So, the best thing to do is try ONE new thing at a time for three. Just a small amount, see what the droppings look like. If no change then a little is no problem. Feed everything in moderation and if you find something they ready like don't over feed this to them. You can us this as a treat to do or have done something you want to encourage them to do. A bowl of extra food should be taken out after 24 hours and you can return it w/ the same thing if you are trying some thing out w/ them for three days to a week. It is best to not change a rabbits diet to much, JUST FIND A FEW THINGS THEY LIKE.
