Not Excited for Wet Food

I don't know why Tyco has no desire to eat wet food. I'm trying to move him off a strictly dry food diet but he's putting up a fight. He just sniffs the wet food and walks away! I've tried several different kinds but continue to fail! Why doesn't he listen to me when I tell him I know what's good for him??

"You want me to eat WHAT?"

Chicken and liver, Tyco. It's good for you.
