Hi everyone,

I've got a pair of gerbils who are fairly young, barely 2 months, but I think the girl, Mia, might be pregnant.
She seems slightly heavier and bigger than her mate, Milk, which is strange becuase Milk is a little older than her and males tend to be bigger. At first I thought that maybe Milk was ill and losing weight but he's fine.
So, could Mia be pregnant? And how can I tell?

Bye
