I wrote a few weeks ago about
Luna's House, a nonprofit that is building a new animal shelter in Maryland including a large section devoted to rabbits. One of the cool things about this shelter (and there are many) is that they want to be a LEED certified building -- very energy efficient, good to the environment, etc.
Currently Luna's House is one of 30 nominees to receive a green roof, which would greatly reduce their costs of building the shelter of course. You can vote here:
