...but I think I'm able to tell the two gray ones apart in good light when I look closely. I hope. Also I'm making inroads into recognizing the black ones without looking under their belly. Still, somewhat challenging. I've decided to name the all black one Kieran, the black with the tiny white belly stripe Oskar, and for the minks I kept the name Rusty (well I think I kept the name for the right one) and renamed the other to Silas.

They are still quite shy, and are mostly camping out just in the upper part of the cage rather than claiming everything, though I've seen Silas (I think) explore a bit more in the lower modules. But their appetite is very good (tiny rats eat a lot, as fast as they are growing). Already they are not really bothered by my hand in the cage, and Kieran in particular even came a few times to my hand to groom it a bit and let himself be petted a little. A super soft fluff ball!
