i don't if it will help a lot but in france no petshop knows about aspen so i was starting to give it up, but i accidentally saw a bag of what they use for birds litter and i'm sure it's pretty the same, it's just called something like "chipsy" instead of aspen bedding. as americans are much more advanced in herpetology than in europe, i believe it's why we cannot find a lot a reptile's material..; people here are much more intolerant too... since i have my sanke i m a kind of weirdo for some of my "friends" and nobody yet wanted to try and touch it but i don't care i just hope dusty mentalities are going to improuve ...
