I quite agree with you. My only issue is addressed in your key phrase, "potential hazards". There is a great deal of difference between something having the potential to cause harm and something being positively linked in all cases to a substance, which is what the title of this thread says.
Thank you, by the way, for being so courteous in your response to my post. Too many times differences of opinion lead to hostile posts and that never works.
Very true, it's definitely not going to be linked to everything. I think chickens have less issue because they don't spend as much time on it, versus, say, small animal pets that spend their entire lives with their faces inches from the shavings.
Heh, no hostility definitely never works
