I have a four year old tiger cat (barn breed) that has been licking himself bald since the arrival of my son. It started in small spots on his back and seemed to be within managable bounds until we moved from Germany to Switzerland last spring. He has now managed to lick the hair off of most of his belly and back legs. I have been to the vet and she says he is healthy but stressed. I have tried new toys and an Atticus play time, hiding treats around the house to reduce boredom, buying a new scratching post so he can look out the window better, even cat massage and hormone treatment. Nothing seems to work. I would really appreciate any suggestions to solving this problem. I should add that he is a house cat and has never been outside. We live on a busy street so going out is not really an option for us. He is also very attached to me and is very rarely out of my sight. Help!
