I use repti-heat cable as the UTH of my tank, and am looking for a new substrate option. Obviously I want something that will still let the heat through.
I've used aspen and it works out OK, I switched to paper towels to allow heat to penetrate more. The problem with paper towels is there really is no spot cleaning. My snake pees (seems to be doing a lot lately) and I gotta take everything out to put down new towels. Its not a big deal for me, but when I'm out of town I need something the pet sitter can easily scoop and move on. I don't want her to have to mess around with taking the snake out to replace everything.
I have some repti-bark from when I tried that a long time ago, I could go back to aspen, or try something else. What about this Carefresh stuff I've seen mentioned on these forums a few times. Is this the right thing: http://www.petco.com/product/113567/...t-Bedding.aspx
I can always crank up the thermostat to get the right surface temp but I don't want to have to set it too high in case my snake decides to dig down.
