Oreo & Ginger are loose when i'm not home, but only because my boyfriend is with them.. but when we are both not home maybe just to go to the grocery store, i let them loose, but oreo has been loose ever since i got him and i started working .. he did fine, but he was lonely i could tell, thats why i got Ginger and now he's happier than ever.
But they terrorize the place as much as they can when i leave them alone, so before i go, i puppy-proof the room that they are free to roam in, and leave their chew toys out (learned that the hard way).. and so far so good
