Laying on the Hearth Rug - OOC
Mephistopheles is an excellent name for a cat.
I thought I'd tell you all what Bones is known for.
Firstly, Bones likes to talk to bugs, cut deals with them, etc. He is a Bugfriend. Bones also likes to squeeze in and around difficult spaces.
Bones might be a coward, since he doesn't like to get into fights unless it's necessary (of course, upon winning a necessary fight, Bones will play with his quarry for some time before the kill, as is right for a cat to do).
Finally, Bones Fleabag might have known a witch or two in his day, and might understand something about poisoning.
