You are doing very well and the fact that he is eating at all, showing that he has some appetite, and is keeping it down is a very good sign. The A/D is packed with calories and I know that a number of us on PT have used it to force feed our cats through some very rough times. As I said, the fact that Sox is eating himself and not needing to be force fed should make you sigh with relief - though I know you'd really like to see him gobble his way through a can in five minutes flat! That time will come, I feel sure.

I'm not surprised that your second vet was angry at the first vet. To have a cat pee bloody and gritty urine and then send home saying it's fine because he pee'd is shocking.
