Zuri Babbling and Intruder Alert?

I took this video in the car with my cell phone so the quality isn't the greatest, but Zuri was being so cute after being so ornery! We were out and about running errands and stopped in show Zuri off to J's coworkers and Zuri was crrrannky. She had only a half hour nap and was tired. We figured she would crash in the car on the way home, but we were much mistaken. She is like me when she is tired: either incredibly grumpy or loopy.
We had an interesting incident happen last night. It was around one in the morning and I woke up to some noises. Our motion sensor light had come on and it sounded like someone was either in our kitchen or outside our door. We rarely have the doors locked when we are home--including at night, so it was entirely possible someone could have entered the house. I am not one of those girls who get frightened easily, but this scared me. I woke J up and he grabbed his trusty tennis racket and we went to investigate. Nothing was found, although we noticed our barbecue was moved off kilter this morning. Our best guess is that some animal was attracted to the smell and wanted a taste. We know there are deer in the area, but other than a cat or a dog, I don't know what it could have been. It had to have been a bigger animal to make the noises we heard.
