I'm not sure? He had a lot of energy earlier but I think it was because he's had quite a stressful day. He took that out on the wheel then ate some, drank a lot and he's been sleeping since. The toys he has have come out of the cage they were sharing so he does have some familiarity.
How would I tell if he's missing Wallace? I'm still only a beginner with raising hamsters haha. I wouldn't trade them for the world though!
