Thanks guys, I'm in love with him already. He isn't in the slightest bit shy (unlike Rupert who was nervy all his life), he's been busy exploring his cage and really loves his wheel. He's also been peeing in his sand tray which is great, hoping it's not a fluke as I really want to litter tray this little guy... Rupert would always pee in his wheel and it made it stink!
Just need to think of a name now
