Sorry, I do not have faith. I have to stick with the science, personally.

People will have to make up their own minds which they prefer.

But I really disagree with advocating a potentially hazardous bedding choice.

It's amazing to me that you have rats with no respiratory problems at all--since they all carry mycoplasma. Unless you got yours from a special laboratory, delivered by C-section.

If you prefer to trust word of mouth over science...they're your critters, do it the way you want. Just make sure the people you are talking to know enough to make an informed decision about it for themselves.
