How can i get my new kitten to eat cat food?

I just got a new kitten who wont eat kitten or cat food, wet or dry. She will only eat cheese or meat. She wont eat if I try to wait until she gets hungry. She just looks at me with hungry eyes and goes off to play. She is thin and so cute I always give in. The vet said to try different brands which we have. Each and every can there is and its a no go? Whats the problem?
