Substrate: Kraft Paper

I also use Kraft paper and love it, I use it in my Boaphile enclosures for my boas.Works great, I buy the 24" rolls from Uline and place the rolls on a cutter. Simply pull out 24" for my 421T's or 48" for my 421D's and run the blade across.

I use 24x36 unprinted newspaper sheets from here http://www.foodservicedirect.com/ind...per_Sheets.htm It figures out to 7 cents per sheet (that includes shipping cost) and it holds up great. It will hold poop from my 20lb boas even when it's wet. ;)
