Just found out a lovely female rat I found a home for has passed away from a tumour. Femi was a lovely, if not skitty little lady who had been put on our local Freecycle due to not mixing with someones other female rats. Turns out, she just needed someone with patience to help her through intros as the lady she went to live with successfully integrated her into a group and she lived there happily for to and a half years.
RIP, Femi.
