THis is a stealth mecha that usually works alone. As you can see, IT's head resembles a panthers. IT also has 2 gatling guns that, when fired simultaneously in rapidfire, sound like purring, another reason for the name. IT also has 2 surprise weapons on its shoulders.
I would like to add that this is the second (possibly third) time that this person has gotten MotD, I not sure that the reason this moc is MotD is because of its build, maybe I'm wrong... but I don't think so.
It may be because it was built in 04 but I don't know.
