Also, about your hamster making clicking noises, pay close attention to how they sound.
If the chattering your hamster makes are soft, then you probably don't have to worry
If the chattering is is loud and agitated, it probably means that they are stressed or upset.
Overall, if this continues, maybe some more research about hamster behaviors? I can totally relate to what you are experiencing. When I got my first hamster, I was sooooo worried about every single thing they were doing...
So just try not to worry too much about this.
