I give my rabbits ordinary wood shavings with hay and straw from the pet shop so they are only small ones and its costing a lot....i volunteer at a shelter and for their rabbits they buy horse shavings so the amount is more and it usually works out cheaper but i cant find any places! i do shred some plain paper sometimes and add to it, that was a life saver in winter and kept them toasty...i was wondering how you guys go about this? i know some of you have a lot of rabbits so do share your tips
