I would ask the vet about an appetite stimulant (if he's not already on one) or tube feeding the cat at this point, eating and drinking very little is only making the issue with the liver worse and will make recovery longer.
At this point Cecil needs to eat anything you can get him to eat, and as often as possible. Cooked chicken breast, deli meat, baby food with no onions, catfood topped with cheese or a tiny pinch of catnip, try a fish flavoured can of Fancy Feast even if he wouldn't eat canned previously - it's smelly & may tempt him, the human variety of canned salmon or sardines etc.
