Oh my gosh...
Well, the fact she is normal weight is encouraging... but she has to be getting into a critical state by now. And I am afraid that if she were going to come down on her own she would have by now. She is waiting for you to rescue her as she does not know what to do. Eventually she will be so weak she will fall from the tree. Falling 30 feet could certainly lead to broken bones and internal bleeding. Unfortunately, it could be fatal.
I am afraid that I have had LOTS of cats face this problem, and many of them have died. They fall, so you can tell your neighbours that this is why there is no skeleton in the tree.
When I have had people faced with this problem they have received aid from:
- fire fighters (I know you said yours refused)
- tree cutters (try call another one!)
- roof repair men
- window cleaners
- anyone with a long ladder and a kind heart
I truly believe that your cat may die if you don't find a way to get her down. How about a fishing net? Could someone get close enough to her to reach her with a 10 foot pole and net on the end? Could you put a mattress on the grass under her and cut the branch she is on?
I wish I could help more! Medically, this cat is in critical distress after 10 days of exposure and no food. I am surprised she is still hanging in there...I truly wish there were more that I could do to help!! Here are links to others who have faced this problem:
