I think her name is going to be Tabitha Tuppeny, much to the disappointment of my OH, for many reasons the following:
* Yesterday whilst doing the photoshoot with her I told her off for running away using her full name "Tabitha Tuppeny get back here!" (to which of course she ignored me)
* the Tuppeny part comes from my favourite childhood book, about a guinea pig called Tuppeny who runs away to join the circus (as you all well know Percy-Roo is famous for his circus tricks!) and the books by Beatrix Potter
So yes her full title is: Tabitha Tuppeny.
Hurrah!
