I know bts.net uses aspen shavings.I use the aspen snake bedding for my boa wich is the thinner cut stuff.They say not to use that on the bts but to use the shavings,more square type.How would one of those square larger chunks not be bad and hard to get through its intestines if eaten?It seems like it would be bad to me.Are the paper products better other than care fresh wich is too dusty for me.Like the paper pellet type.I stood in pet co for an hour reading these things and got none.I had bags of the slivery aspen at home but read just incase and found they dont recomend it.Kind of in a hurry here,lol.Help.
