The noise my cats make when they are scarfing down their food. It sounds like a cross between the word nom and a deep growl.
I place tuna on a plate and my kitty Oscar goes nuts. He then eats the tuna in a very fast manner and makes a growling noise that sounds just like "om nom nom nom."

The nom nom nom is no joke.
