Yes, I just went through all of this. My cat, Penny was 14 years old. She lost so much weight and could not eat one bite of food. We also gave her IV's and even put a stopper of Hills' special diet down her throat every 3 hours. She did not eat for 9 days and finally we put her down about 10 days ago. She was sitting on my lap purring right before we took her to the vet. He told us that she had gone too long without food and her entire body would be shutting down. She was already vomiting all over the house and I just could not let my precious cat suffer. It has been heartbreaking since she is gone and I went out to the Rescue league here and got a beautiful young male cat 2 days ago. It truly is not a home without a cat in it for me. My heart goes out to you as I know exactly how you feel right now. I am so sorry.
