Now that depends entirely on the species. Syrian hamsters shouldn't be kept together, but my guess is that Addie knows this and her hamster is one of the species of dwarf hamsters who are quite happy in groups.

Unfortunately, it's difficult to intorduce an adult to a new cagemate, so your hamster is probably going to be single for the rest of its life.

I agree that its world has been turned topsy turvy by two major changes recently and he's probably FREAKED OUT! Give him some time, bribe him with (Healthy!) food, and maybe use a cup to scoop him out for awhile. When I worked in a pet store I found that to be one of the more effective ways of handling jumpy or stressed hamsters.
