my very sick kitty

I am so upset, some of you might know that I have a very sick kitty. Things are not going well for her right now. I just got back from the vets office (one more time) and they kept her. Her only chances of living now is a feeding tube. They are operating on her as I type and she is very weak. I don't know if she will make it through the operation. If she does, I will have to feed her through a tube for about 6 weeks. I just don't know how I am going to do it..I mean, I will do it, but I am praying that I have the stomach to do it. I have helped out and nursed many critters back to health, but this by far is the hardest thing. It was either do this or put her down and I couldn't. The vet told me if she can make it through the operation she will have a 60% chance to live. No one really needs to reply...I just had to get this off my chest to folks who will understand and I am so scared.
