lisalisa - I know how you feel - rabbits do look as if they need a lot of excercise, don't they? Is yours one of those runs that has a removable front for placing as an extension in front of a hutch? Could you get another one and ad it to your run as an extension? OUr rabbits have the full run of our shed, with a hatch through the wall into a biggish square run, and i still see them peering at the grass beyond the wire, trying to reach grass which is out of reach.
