No answers for you on anaemia or anything right now, but before I try and get some sleep (it's 4-30 am here!!!) just wanted to say what a wonderful person you are for all the care you have taken with Silly. Esp the syringe feeding, hard as it has been, may well have saved his life, and persisting in saying to the vet you felt there was something bothering him and getting them to check his mouth - not giving up as you could have done. Silly is a very lucky cat despite all he has just been through and I feel confident he will be using all the energy he has to reward you with purrs and demands for fur-attention. I can only imagine how much relief and happiness you felt when you saw him jump up on that chair of his, meowing and chatting away, and even snacking on some more turkey. Hoping this is Silly turning a corner and that you will see him go from strength to strength now that nasty suture has been removed.
