I hope Ash is doing well - I am really hoping that his eating has improved. When my Sydney was going through her chemotherapy, she had a couple of bouts of not eating, where I too tried every kind of cat food available. Nothing seemed to work - then someone on the PetTalk thread suggested baby food. I went to the store and bought turkey and chicken flavors and she ended up liking it a lot. I know it is not much, but it is worth a try. You and Ash are in my thoughts and prayers!
