I have been putting my piggies in an outdoor, secure run pretty much daily. I have found out that they both absolutly adore grass, and they stuff their faces with the stuff when in the run. The thing is, I'm not sure wether the grass counts towards the Vitamin C count or not, if it is ok everday and if I should be giving them the normal portion of veggies, or maybe a little less so they are not over eating?
