Greetings Everyone,

I'm new to this group, but I have a question and can't seem to find any
answers in any of the posts so far.

My friend's cat "Easter" (long story on that one) is pulling her hair out
of her back.  She did this last Christmas, and is doing it again this year.  

Her back eventually recovered last year.  We're not sure of the cause at
all.  She's an indoor cat.

I've heard suggestions that it could be fleas, dry weather, and stress.  
Any thoughts you could offer would be appreciated.
