I'm sharing some photos, because I can 
Ruby jumped into DP's jumper today for the first time, we are super chuffed by that, she's going slowly on the socialising front but is getting there :)
We have Howl (one eyed dark rat), Haku (sandy coloured rat with black eyes), Ruby (brown hooded rat) and Nibbles (strawberry blond hood).
Howl and Haku are 4mo boys, we've had them from 6 weeks and they have grown significantly! They are huge. We're hoping that they become a pair of those huge fancy rats you see
Ruby and Nibbles are a bit over a year, we've had them for just over seven weeks. We've only just started getting Ruby to trust us over the past week or so, Nibbles has only really started being very comfortable with us over the past couple of weeks too, though we've been able to hold her for a few weeks.
