Black cat
Late in the night when the ghouls were all awake, a graceful black shadow slinked between the shadows that the forest offered. The creature was a black cat with silky rich fur and ears that were longer than ordinary cats.
The feline snuck past a ghoul and leapt atop a tree. From that position, it jumped to the roof of a cabin and settled down to eavesdrop on the conversation that was happening in the room below it.
"-your ghouls haven't found the rat. Do you think it must have already escaped?"
"My babies are not dogs. Their sense of smell and sight have been sacrificed for viciousness and strength. How do you expect them to hunt if we don't give them direction?"
"Which is to say they're no more useful than puppets. I can't believe we've wasted so many years perfecting the technique only to end up with such useless grunts that only know how to kill and eat."
