Why does my cat growl if I try to take her food?

My cat is a pure bred Devon Rex straight from the breeder so there should be no history of abuse or food issues. She is sweet and loving but if you give her food and then try to take it away she will grown and even hiss. (Never bites or scratches though she is a good kitty) There is always food out so it's not like she is starved. It's more funny than anything it's kind of like a dog. I just wonder why she does it.
