OK thanks for the advice everyone...I think I remember reading somewhere that they ate their babies...but I think it was Syrian hamsters.
Speedy has been eating a lot, but she is sooo small, Perrie is like twice the size of her. Plus, she has been eating a lot since we got her. Maybe she's still a little worried or scared.

On the bright side, I wanted a male to begin with...and now I got one. I'll still keep the name Perrie though.
