My cat plays with the rats and mice she catches before she kills them to eat. Even then she rarely eats all of the animal. Brains seem to be her preference since she eats the heads and leaves most of the rest on the porch. Some of the small animals she catches escape because she gets bored or distracted when someone comes out the door to see what all the commotion is about. With that said, you're right, it doesn't make any sense that a rat would live long enough to catch anything in an encounter with a cat.
