Answer 2

I have 2 female rats (Arwen and Gracie). Arwen has made little hiccupy noises since about a week after I brought her home (they're both about 7 months old now)
I took her back to the store to get her checked out, they said she was fine, took her to the vet 2 weeks later when it didn't stop and he said she was fine too.
She still does it, usually when I open up the cage or is she's sitting still for a long time.
People tell me rats aren't supposed to chatter either but both of them chatter at me, every rat I've ever met has chattered and squeaked so I don't think it's a big deal. :)
