well my yogi is the same way he does not like the healthy food he likes the bad foods. lol i use to change his food every month or he wouldn't eat. you do need to find one and just stay with that one when he doesnt eat dont mind it. i just left him alone until the food was eaten he will eat when he knows he is not getting what he wants. they are little brats when it comes to it lol
