Okay, the more I read the less I know! LOL Some sources say shavings right from the beginning because paper gives them splay-foot. Others say paper first and then shavings because otherwise they'll choke on the shavings. Can I use lizard liner (paper with little knobs on it so it has traction) for the first week and then switch to shavings? (ignore lizard- just look at the liner) Would that be a safe option? Or how should I do it?
