Hi Daniel!  I have the same exact problem from my little beast...she loves
to eat cloth!  Socks, blankets you name it.  I'm starting to call her " The
Moth "  I have also heard that it's not good for them and it scares me to
death when I've heard about someone's ferret almost dying from a blocked
intestine ( which, I've also heard happens VERY easily ) but so far ( knock
wood ) everything has been able to pass right through her.  It does worry me
a bit that you say her poops look normal.  When mine has eaten some cloth,
it always comes out all rolled up in her poop.  Keep an eye on her poops and
see if you ever see any of the eaten cloth in them.  If she starts acting
weird and like she's in pain make sure you get her to the vet.  The only
solution is to make sure you keep all cloth away from her.  It's hard
because mine loves her blankets, but she'll eat it to pieces if I give it to
her.  ( watch out...they're pretty sneaky!  No matter how careful I am I
always seem to find one of my socks, half eaten, behind the couch.  I swear
she must have a stock pile somewhere )
 
Good luck and I hope everything works out Ok!!
