Kitchen area. We cut a square in half for the hay rack. I have access to power tools so we filed down the sharp edges and put them on the inside just to be safe. I have a second water bottle, but they don't like it much. I'm planning on getting them a new one like this one soon. I'm also thinking about using some bricks to separate the sections. Any thoughts on the safety of that? I worry about what chemicals might be in them.
