they can go off their food, and when they r due to give birth a few days before they get very affectionate and wont leave u alone, she obviously wants u 2 b with her when she has the babies, u will find wen she goes into labour she will b happy in her box, so long as u r with her, mine got out every time i moved away, so had 2 sit on floor next to her untill she had hers,
but was happy for me 2 let her get on with it after the 1st 1 was born, but i stayed with her all the time,
Hope this helps,
