Taken from their website:
"RABBITWISE® is an all-volunteer, non-profit organization (501c3 public charity) whose primary client is the domestic rabbit. Our mission is: to PREVENT irresponsible acquisition and care of companion rabbits; to improve RETENTION rates of rabbits already living in homes in order to avoid them being relinquished or abandoned; to EDUCATE persons who live with, shelter, and/or treat rabbits to give them the best care possible; and to EDUCATE and ADVOCATE for the broader welfare of rabbits in general.

RABBITWISE® is primarily concerned with promoting the welfare and increasing the quality of life of an individual, group, and/or class of domestic rabbits by:
-offering educational, consulting, coordination, and/or support services to potential and current rabbit guardians;
-offering educational, consulting, coordination, and/or support services to the rescue, shelter, veterinary, and advocacy communities; and by
-educating and advocating publicly and privately for humane treatment of rabbits locally and nationwide."
