DIZZLEWONT EAT :( CAT

My friend has a cat that she has had for a few years that as of two days ago stopped eating. The cat seems to be pretty lethargic latley and not quite acting itself. Its just small things like not wanting out as much and just lying around. She also said that dizzle(the cat) is having more "eye boogers" or drainage than normal. Nothing extreme, the drainage is just whiteish in color no brown or reddish colors. Dizzle seems to be drinking still or at least still peeing in the litterbox. Please any advice or at least were to start woudl be great. This is an indoors and outdoors cat, and there are multiple cats in the home. They are all very well taken care of , and the food has not been changed recently. Please help us and thank you again so much.

He really must go to the vet if he doesn't start eating ASAP.  Cats who stop eating are at increased risk for hepatic lipidosis (fatty liver disease), which is a deadly disease.  The cause of the inappetance could be something minor, such as an upper respiratory infection, for instance, which could prevent a cat from smelling his food, but if fatty liver disease ensues, it will require hospitalization and in house therapies.
