I hope the vet has discussed a feeding tube for Corkscrew. Often with the 'fatty liver disease' (hepatic lipidosis) the cat feels sick, doesn't eat, liver gets inflamed, makes cat feel worse, cat doesn't feel like eating - - the one thing that the cat does need is to eat. If a feeding tube is an option for you, I would recommend you go with this treatment. Feeding the cat is relativly easy. It will get enough food into the cat that he needs. The tube feedings may go on for a month or so. The longer a cat goes without adequate food intake, the worse the disease becomes. Best of luck for you and Corkscrew.
