My theory is that the cheap canned cat food has something in it like a drug or something that gets cats addicted. I can contest to that because Max was brought up on junk canned food. When I adopted him 6 yrs ago it took months for me wean him off it for his morning meal. I tried to get him to eat the good stuff at night without the Fancy Fiest but no luck. So now my 10 yr old Max gets high-quality wet food mixed with high-quality dry with just a smidge of FF on top. Then he will eat the whole thing.

And yes, he meows continuously as well, but I think it more of a "Mommy where have you been....we've been starving all day. Now gimme dinner......NOW!"
