Only when I take her out. Or, better said as, only when she musks, which is almost all the time I take her out. Only recently she started calming down with the musk, as long as I maybe caress her a bit before taking her out, and then take her out slowly. Previously, I used to go in and just get her quickly, giving her no chance of fleeing.
But... if she musks, this happens. And, even if not, it'll come out a bit. Eventually it goes in. While handling, its always out... more if musking, less if not. When not handling, I can't see it at all.
