Talkative hamster?

[Burakki]

I’ve had my Syrian boy since October and the last couple of weeks he suddenly got talkative. He often makes these weird quasi snorting quasi sneezing sounds, as if he’s trying to clean his nose, but it doesn’t seem like he’s ill or actually sneezing. He’s always been a bit skittish and shy, but he didn’t have any stresses lately and he seems to make these sounds without any scares. He easily climbs my hand and takes food from me, acting very tame. The sounds start out of nowhere, sometimes he would make them even while sleeping.

Did he just got talkative with age (he’s about 4 months now) or should I be concerned?
