Nancy, I am so sorry that you and Roscoe have to go through this ordeal. I would call the best lawyer you can reach and start a class action suit if there is none. Also, if you have a no kill shelter in your area they may have a less expensive Vet on the staff. They can also tell you about rescue groups who may be able to help you financially. I have found some lists online This one is the one I find easiest to use: http://www.petfinder.com/pet.cgi?action=4. Perhaps you can get some info from them that will make it easier for you to care for your precious cat.
