I've been on here for a while and I haven't introduced my herd yet. Now it's been a bit of a rollercoaster so I do apologize.
Eileithyia-Eris and Jupiter
On November 1 2020, I adopted 2 Guinea pigs who I was told were both 9 week old males. They were were very skittish. After a while it became apparent that one was definitely not a boy and looked a tad round. I separated them and they lived side by side until just before Christmas the same year.
Here they are when they arrived (before the separation) (Jupiter on the left and Eileithyia-Eris on the right) :
And after 2 weeks post separation:
Jupiter

Eileithyia-Eris
By the end of November Eileithyia-Eris was 13-14 weeks old and looked like this...

Cages had been baby proofed as well as having a few large, comfy hides. I was very anxious at this point and spent a lot of time with her just in case anything happened. 1 in 5 births go wrong!
