Gus and Lucy are outside full time now. I've been using grass clippings for bedding as the pen has a concrete bottom. Is there anything better that I can be using besides the grass clippings? Once summers over there wont be any grass clippings left to use so i'm looking for something a little more permanent. Heres a few pictures of the pen it's about 20ft. long and about 10 ft. wide. Theres a drain just outside the gate that leads to the sewer.These pics are a couple of months old and I switched out the shavings. Any advice would be greatly appreciated.
