Paper Towels vs. Aspen

[snakesRkewl]

But I read that paper towel has extremely toxic chemicals like Zinc..it will be very toxic to animals...

I read the glue that binds the paper to the roll and the glue used to hold the roll together contains zinc.
Not the paper towel itself.

I've used paper towels for 3 years and have seen no effect what so ever, just super healthy active well eating snakes that breed like rabbits
