There was a cartoon series about a seriously messed up cat. Can’t remember the name, but this cat was awful. Anyway, one time he hocked up a hairball in one of the panels and the sound was spelled “Kvaaaacccckk!” I always remembered that because it is very apropos.
Bloom County. Bill the Cat. He supposedly escaped from some sort of medical testing lab where they’d removed his brain and replaced it with tater tots.
