Have you ever seen a cat eat a mouse, or similar small rodents?
After it stopped playing with the food, the cat swiftly bites down, and kills it either by breaking its spine, or biting down on its head.
Then, the cat starts to consume the carcass. There's no noise, until you hear a loud *CRUNCH*, and the rodent's head is missing. After that, it's crunch after bite, until the cat slowly chews the victim into edible chunks.
Sometimes, the cat leaves halfway through. What you get is a mouse ass, with guts sticking out the middle, blood seeping into the ground, where the cat left it. Rotting away into oblivion, because the cat will not eat the rest, even if it gets hungry later.
After all that, if you still find an antropomorphic cat eating people sexy, I think you have a deeper underlying problem.
