Hi there! Sorry to hear about Yoda's problem. Thats so sad but it so wonderful that you rescued her!! How miserable she must have been. Poor baby!!
I really have no idea how you can find a vet specialist but I wanted to let you know about a wonderful website called Imom. The web address is www.imom.org and they may be able to help with financing. I really don't know how it works but everytime I have checked the website it seems like they are doing some wonderful things. It's just a thought and it won't hurt to check it out.
We will be praying for Yoda and for you. It's hard to care for a sick kitty that still needs help. Bless you for caring about her and loving her.
Please keep us posted!!
