Pet stores sell this, but they don't know that it's bad to give your hamsters bedding fluff. They may choke because the fibers in the bedding sheets will get stuck in their mouths when they try to make their beds. An easier and safer alternative is to use ordinary tissue paper. They can shred it up themselves and there's no danger involved.Please do your research before buying animals and animal supplies! It will be beneficial both to you and your new critter friend!
