How strange! I had no idea cats could get such a thing. You know we went through a spell where Magoo was pulling out his hair in clumps but I associated his with stress. I think in Magoo's case it was because he has stopped but I never would have thought about anything else.
If I'm not mistaken Kim's Tucker does that. She will probably be interested in reading this.
Good luck and keep us posted on how things go. Thanks for the information.
