Meet Sock! I adopted him yesterday. He's currently six weeks old and I think he's a campbell / winter white hybrid but I'm not too sure. He's been tamed a bit already and he doesn't mind me sticking my hand in the cage but then just ignores my hand, so I'm not going to bother him too much for now.
I'm keeping him in an Alaska cage, which still needs a few small things (my package has been delayed.. should get it tomorrow) but he's very fond of his wheel and made a hideout by burrowing so he doesn't seem to mind!
Here are some photos:
