The way to find out about the kitchen roll is to put it in water and see if the colours run.. if they do dont use it... best thing I can think.. and never heard of it being called towel paper before Dex.
I am sure an adult snake could eat newspaper but I know where your coming from. Did you see that Burm in USA that ate an electric blanket?! :shock: I keep my adult boas on towels. Not paper ones actual towels. Well some of them anyway.
