straw

So I live in the us and it's winter where I am looking at bedding types and I bought straw bedding and have an abundance of blank white printer paper that I can shred up and want to know if it's safe

Hi, I’m torn between using straw or wood shavings from Pets at Home? I was just wondering what all of you use in your bed and if anyone knows what type of wood shavings Pets at Home sell as we can only really use Aspen. :)
