China was always the timid one who used to follow Harvey around (he has became much less nervous now, but is nearly five and a half years old).
It's funny how they develop new habits - China occasionally has mad turns biting at the carpet or wallpaper when out in the living room exercising, then might not do so for months at a time. More endearingly, Harvey (RIP :0) in recent times got to know when I picked China up in the living room to return him to their cage, that the door would open and Harvey could go through to check out the bedroom. If it was only open a little, he would paw at the door edge like a dog to be let through! He did this almost every time during his last few months and liked going under the bed (though he didn't hide under there). Harvey also quickly sussed out that, after a while, he should wait in front of the cage when I was putting in parlsey to China (who was already in the cage), to be picked up, and he would get his!
