The pet bedding I have is all wood but a bit of paper isn't a big deal. I put a bunch on the surface and let it sit for a bit, maybe 30 seconds. It will begin to smoke and smolder. I then start spooning lead from the pot and pouring it thru the wood. Once it starts to really smoke I light it with a match, mostly to keep the smoke down. Keep spooning lead thru the flux. Once the firs is out I stir like crazy bringing metal up from the bottom of the pot. I then skim the wood debris off the surface. It should be light stuff as it should have no discernible metal in it. If there is still a metal sludge on the surface I wait to skim til I repeat enough times to get that melted in.
