Oh my,
Thanks to you all for answering so quickly! Mater's hatch date was 2/6/09. So, Caitb, ours are very close in age. After reading and thinking about it a little more, it is possible that headlights could have caused a shadow against the blinds. Their room is in the front of the house. The room has a huge window with an arch. We are one of the entrance homes in our subdivision and anyone that turns in will definately shine their lights towards our home. This happened around 1:30 am. Mater's cage is not normally covered but thinking about it now, it would probably be a good idea. We have had him for 1 month. His name comes from the movie "Cars". The tow truck in the movie was named "tow-mater":..."mater" for short. Cute, cute movie. Also, one of the first veggies he ate was a tomato. Seemed like a good fit.
Thanks to you all so much! Will definately do the photobucket thing and post a few pics.
