I am going ot use pine shaving on a painted plywood floor. How deep should the pine shavings be? Should I go ahead Wednesday evening before I go to bed and set the food and water in place or just wait till I get them home? Should I just put new shavings on top of the older ones, or how often should I clean all the shavings out and add new? That is all I can think of right now, but as time keeps drawing near I may have more. I have never had any type of livestock in my life so I am getting a little nervous. I have read and studied for the last 2 years, but now as the time draws near I seem to have forgotten some things, and second guessing myself on other things.
