Remy learned to climb out of his ex-pen at around 7 or 8 months old. After coming home numerous times to find him running around (haha) instead of snoozing in his playpen, one night I placed him in the pen while I was at home so I could see how he did it. He literally just scaled right over top of it like a little spider and came running over to me so proud of himself. Luckily, by this point he was pee-pad trained and he was never a big chewer so I just started leaving him out while I was gone. He has done fine
they are such little smarty pants and they are so cute that no matter what they do, we just cannot be mad at them haha
