I am sorry you are going through this, but just want to re-emphasize the importance of making sure he gets his normal daily amount of food syringe fed. If he normally eats 5.5oz of food that is what you need to syringe feed. I went 36 hours without eating on my boy before I started syringe feeding him. Fatty liver is a real risk and I have seen it in cats who don't eat their normal amounts in as little as 48 hours.
