Yeah I think so too
I got home from work last night and he was definitely missing my company. Almost jumped OUT of his pen....silly boy.
Looks like he decided to poo in his play pen too...first time I had left him for more than a few hours in it. What a stink!
He also surprised me by figuring out how to jump up on the bed!! my bed is about 3 ft off the floor but 2 feet up is a shelf kind of thing. He figured out he can jump there first then up onto the bed

Surprised the heck out of me and my GF! He hasn't got the guts to jump down though, thankfully!
Finally, I had to dislodge a piece of food from his throat yesterday too! Scared the crap out of me. He was inside eating and I was outside on the porch. We were about 10 ft away from each other. He came running outside gagging and drool coming out of his mouth like crazy! I FREAKED out and started to go get him and he ran away, like he usually does, but I caught him and did a little squeeze on his chest in the place where I remember reading. I don't know if I dislodged it or he did.
what A day yesterday! I swear. Saving from the choke, cleaning poop in his pen and watching him learn how to get up on the bed....
