Peeking into the rock

I came home just now to find that somebody came into my house while I was gone and closed Truffle and Percy into the front bedroom (guaranteeing that they will bark the whole time) and closed the back door (guaranteeing that Lola would pee and poop in the house).

I have a slight suspicion about who did it -- someone who has occasional conditional access to my house and may have just lost it -- or someone who has occasional access to my house and I would forgive after explainign exactly why they can't do this -- or it could be the creepy neighbor-- they were howling when I left.

Edit: actually, I think the back door I may have done myself.  I closed it temporarily at some point in the morning: I thought I opened it again before I left, but maybe not.  But for me to have accidentally shut them in the front bedroom, I would have had to open and then close that door at some point, and I had no reason to.

Edit, later: something happened this evening that makes me think it was me all along after all.  I found Truffle in the front bedroom barking.  I never opened the door (it traditionally has difficulty staying closed, but I supposedly know how to close it so that the dog can't open it).  So I think what happened is that Truffle let herself and Percy into the room as I was getting my stuff together and I absently noticed that the door was open but not that there were dogs in there and closed it without thinking about it at all.

That explains why I heard them howling when I was leaving, though.
