Hello everyone,
this might be a silly question, but how do you tell if your
Guinea Pig is pregnant? The signs that I am seeing (And smelling) is
that she is getting wider (as apposed to rounder/fatter) and when she
sits on my hand, it feels like movement from her belly. She is also
giving off a different odor.

If she is pregnant, what precautions and measures do I need to
take?
I have already gotten a second cage to keep the pair seperate
if/when she has babies.

Thanks in advance.
