Sillypuss is not tied to any specific household or even an item; they seem capable of moving between worlds without affecting their form or abilities. It would be fascinating to talk to them about their strange properties...tragically, Sillypuss is a glowing cat of few words.

I suppose my only consolation for this is that nobody is, in essence, truly ever original in their ideas, everybody derives inspiration from someplace no matter how remote or infinitesimal (perhaps a microscopically-vague recollection of Ellis' work spoken from somebody else's mouth at one point in time weaseled its way into my subconscious, fostered itself there for years, and that's where I conjured the foundation for my novel) and that rationale is extended to Mr. Ellis himself.
