Ok.
So, following everything you said...
I'm going to disconnect the wheel from the older cage and connect with the new one.
Now, with the mom and babies inside? Or should I put the mom first on the new cage and then, after 5mn, connect the wheel with the babies to the new cage (that already has the mom inside)?
Thank you all for your help
By they way, Souffle, she is chewing the plastic between the wheel and the rest of the cage... A "decoration" there is inside the cage... Not the part that supports the wheel
EDIT:
I don't look to much... I just use a lamp (outside, pointed to the wheel) to see inside, when she goes to drink some water (and I usually only look a few seconds).
"Can you see them now wiggling around?" - Yes, I saw them wiggling around
"For now you need to make sure the pups are getting fluids. Chop up cucumber very small and try and push it in to the pups." - I don't want to push food inside the wheel... I'm almost certain that she would freak out
"Do they look all cramped and smelly in there?" - I'm certain that they are dirty in there cause once, when it was day, I arrived home, went to see the male and when I looked to her cage, I could see the Mom "cleaning" one of the babies (I'm certain that she didn't do anything bad to it cause it's the only white one in there).
