I've only seen one case of an animal eating hair.  In that case it was a
llama who would pull out chunks of hair-either one of his companions or his
own-it didn't seem to matter which.  Then he'd chew and swallow it,
 
The cause of that was not determined.  However, there is a nutritional
deficiency that can result in hair eating.  I think it's zinc, but I'm not
sure.  (Can someone check me on this?)
 
If that's it, maybe whiskers have a higher concentration of zinc than
regular fur.
 
It could also be something relatively benign, like perhaps Errata doesn't
clean her whiskers well and they still have some food or Ferretone on them
and are just tasty!  But if that's the case I'm not sure what to suggest.
