Currently, feeding someone else does not make a sound. It should make a sound just like eating

A simple fix would be to make it that you have to eat a certain amount of human flesh to catch kuru, say a whole steak, so if someone manages to slip you a mouthful by sneaking, you have a chance to turn around and deal with them. Similar to the way you can eat with cholera, but too much food makes you vomit, so with eating human flesh (a whole steak gives you kuru) except the counter does not ever decrease so by the time you have eaten a whole steak, you have kuru no matter how long you leave it in between bites.
