besides Pine & aspen shavings, what should be avoided in regards to substrate for royals? When I had my corn, I used old newspaper shreds before moving on to shelf lining with various sized rocks to assist in shedding and basking (not heat rocks). But I was thinking of finding something abit more pleasing to the "human" eye. I don't want to use any type of sand....I have serious issues with it, but I don't want to rant and you don't want me to either...so that leaves pretty much everything else. The last thing I want is to get the enclosure built and then the snake to come down with something if I could have prevented it. Any suggestions would be most welcome, with the exception of that darn sand that causes way too many difficulties for me. I know that whatever I decide to go with will have to be changed and yet, at this point I don't mind the work it takes to keep an enclosure clean and the snake happy/healthy.
