all 3 of my girls are on NV raw and i inspect their food everyday. So far i haven't seen huge bones fragments in their food. I have seen small ones and i know that it is supposed to be there. Tumi and Gracie have been on it for 6months now and i love NV. I just switched my little Tsubi to raw and she also loves it too. I guess you just have to check every time just in case there is a huge bone fragment. So far, i have been lucky.
