please save my cat Pearl

Hi, my cat Pearl was bitten last night by a dog and is in the emergency vet. Two very sympathetic people have put up more then $2000 to have her worked on so far.   Pearl is my only animal and in my 32 years of living, owning many cats and dogs, and has been the best cat I've ever owned in my life.   I would never do anything like this unless it was an absolute emergency.  Please help me.
Thank you 
Chris Marshall
