We have 2 guinea pigs around three months old and bought as females.
One of them is very passive, the other is has periods of bad temper.
This manifests as "rattles" and pacing behaviour and over the last few days
attempts to bite the other pig.
This behaivour is leading me to suspect that "she" might be a "he". Is this
kind of thing
exclusive to males or can the girls do it as well.
I have checked the visible gender signs and remain unconvinced.
Grateful for any info.
