i was wondering about this the other day and i was thinking well if you leave it til pups are born then you're disturbing the nest, but if you do it before hand, doesn't she go mental?
Are the pups ever born early? I mean what if you lifted her out to clean the cage and she started to have the pups! Or would it upset her cleaning the cage if she's made a nice nest and stuff? could you clean 3 days before instead, or does it make no difference?
i'm really nervous about having my first litter! last time they just got on with it without even telling me!
