Hi!
I'm new in this forum and I saw here some pictures showing a ramp covered by Shelf Liner. I was wondering if is it safe to my guinea pigs to use Shelf Liner as substrate. I mean, my idea is to have some paper towel layers on bottom and Shelf Liner on top inorder to avoid piggies to stay in contact directly with the humidity.
Does anyone know if Shelf Liner is safe to use in a piggy cage?
Is Shelf Liner "non-toxic" material for guinea pigs?
