today, when my hamster was just exploring, playing, digging and doing all his hamstery things, i realized that he was shaking, it was not cold, and he was also quite jumpy and scared... he is tamed and confident around people (climbs straight onto our hand) but today he seemed scared, i dont know what to do.
Because of this I've done a quick health check (looking at him through his hamster ball) and he seems fine... what shall i do?
