Cool so what i have in mined seems to be rightAngelmouse said:I have exactly that in mine Mark!
The 4-5 does seem fine in it you may get the od squabble now and then but that usual in any cage. I do have a buck in a Rody but it does seem very spacious for one mouse, and if its need for more does then I down size him to a tub.
Two birthing does do really well in these I find.
So there you go, I'm currently converting some tubs and getting rid of some wire cages but will keep the Rody's.
