Number 1 for sure. I have a box sping and a mattress and my two canine girls are free to hop up and join me at nights. They are free to sleep in my bed. I love cuddling with my girls at night, it makes me feel at peace.
Exactly, my girl has a cage covered over with a blanket so she can hide away, but the door is removed.
I think the bottom photo is an s&m thing and the cage is for a person, as there are doggie stairs to the left.
