Rabbit not using legs

Question
My rabbit was fine early today, when we check on her later tonight she is dragging both back legs.  She is not in any pain and is not eating.  What could be the problem?  

Answer
Dear Rachel,

Please read this immediately:

and especially the linked article by Dr. Susan Brown.  Then get your bunny to a rabbit-savvy veterinarian NOW for immediate treatment:

If this is due to a traumatic injury, the sooner anti-inflammatory drugs are administered, the better the chance for full recovery.

I hope he'll be okay.
