Quilly does something similar lol only I find what Quilly does to be kind of weird. HE doesn't rip up just random tissue paper, he goes for the paper towels that are his "potty place". He uses them to go to the bathroom, and they are under his wheel, but by the time I wake up in the morning I see that he tore off tons of the tissue and has it wrapped around him inside his igloo.
I don't know what he finds so appealing about it however. Oh well, he's a character!!! All hedgies are though, aren't they? lol
