Hi, I actually went to this site to find out more about my own cat's recent diagnosis of Wool-sucking disorder. My cat, Oliver, started out by eating my hair while I slept--he also took out some big chunks. Then I noticed my carpets were missing pieces of their fringe. Then I noticed the lace on my pillowcases were getting frayed. Then I saw my duvet cover was missing its corners. And then one night I climbed into bed and pulled my sheet up oover me only to find a hole in my sheet. Since then he has eaten holes in some of my clothing, my couch-- anything fabric.
My vet said he had found out about this at a seminar and it is called Wool-sucking disorder. Now my little vacuum cleaner is on anti-depressants! Hopefully your cat just sticks to you hair. But if any one else is dealing with this I would love to hear from you. Right now I am waiting for the medication to kick in and hiding all fabrics!
