Ways to tell if a bird was dispatched by cat or bird of prey?

With cat attacks, I often find the whole body, with either a broken neck or a missing head. If you’re willing to look closer, a cat’s canines leave distinctive puncture marks as well.

Why would the cat leave the body ?

many years ago we found the head missing but the body of a Eurasian Wigeon -? So if what you say is correct then a cat attacked it but why would it leave the body

thanks
