A surprise welcome at the door when I came home today

So I drive into my garage, click the garage door opener to close the door, gather up my belongings after a day at work and open the door into the living room.  There was this black Lab, tail wagging right at the door,excited to see me.

"MOLLY!" What are you doing here?  Why aren't you in your cage?

I fully expected to see trash cans emptied and chewed up paper all over the place.  But, no, the house was exactly as I left it this morning, with the one exception that Molly was not in her cage.

Has she learned to unlatch her cage???

I don't precisely remember latching her cage door this morning.  It is one of those things you do without thinking, by habit.  I don't even have to tell her to go to her cage.  She knows that I am about to leave and that when she goes to her cage, she gets a treat.

She has an oversized cage (for her size) with plenty of fleece blankets thrown in.  On occasion she will even go there when I'm home, for a nap.

After checking the house to make sure no one had broken in and taken anything of value, I determined the real bad guy here was me for not properly latching her cage door.  This time I got lucky.  She behaved herself while I was away!
