My oldest cat, hes 4 soon refuses to eat canned. Ive tried every single brand I can find from crappy to quality. Pate, slices, chunks, fillets...anything. He licks it for a couple minutes then walks away. I feed canned food at night with added water to try to get more moisture into their diet and want him to eat it to. Does anyone have any ideas on how to get him to eat it? I even tried the starve method and he went 15 hours without eating a thing
