Do you know where the weasles came into? What is your rabbits cage made out of? did the weasles make a hole in the cage? I used to have a rabbit, and to keep preditors out, i had this peice of wood that would go over the chicken wire part of the cage. Sadly my rabbit died at age 2 (not cuz anything ate it) I think it got sick cuz it lived outside in the winter. My duck uses his rabbit hutch sometimes and nothing has got him ever since. Hope that helps.
