Hi,
Sugar's Mom, mine are five weeks old, they can fit their heads through but their shoulders won't fit. I was worried about it, but the first thing they did was try to get out. They like to stick their heads out and bite at their mom when she comes up and checks on them.
They are smart little guys, I've got them a bed and a play area, and a potty pad on the other end, and they go off to the potty pad already. Or wait until I let them out to play, they'll get right outside of the pen and potty. At least it's not in their cage.
