Is she gravid? (clear photo included)

[Jhill001]

She has been bred 4 times. The first mate was on 6/4. She is not willing to eat now but fortunately she ate an adult mouse 2 days ago which you can see the plump on her body. She is over 600gram and I wanna know whether she is gravid. Thank you.

You from over the pond cause 6/4 here means June 4th?

No clue but if shes putting on weight really fast that would be a reasonable conclusion.
