This is the first pic of my girls cage, i have made a couple changes to it and i will update my picture once i figure out everything, as they grow i will need to expand also.
I have the same fleece! I got it on black friday for 2.99 a yard plus 20% off. I love your setup, but as they grow(now would be a good time, because babies are more active) I would increase the size to a 2X4 or bigger.
To funny I bought mine for 2.99 plus the 20% off also at Joann's on black Friday. Well I have plenty of grids I'm just trying to figure out where to put the grids, I'm running out of space I have my boys cage and the girls cage is on top of the right side of there cage, I have been thinking about a cage that I can stack but I just don't want it to be a pain to clean, but I will figure something out.
