ohhhh-possum?

So, I'm sitting here in my office, catching up on my blog-reading, when I see something out of the corner of my eye. I look outside and this is what I see just a-ramblin' past my window....

...an opossum momma and her baby. Momma was about the size of a really fat cat, maybe a 16 pounder.

I ran outside with my camera and came up behind them. Momma gave me the stare-down, but otherwise, just went back to foraging. I got a bit creeped out after a few minutes. Do opossums chase humans? I don't know, but I didn't want to mess with a momma and her baby. 

Here's the wiki info on this critter:

The Virginia Opossum (Didelphis virginiana), commonly known as the North American Opossum, is the only marsupial found in North America north of the Rio Grande. A solitary and nocturnal animal about the size of a domestic cat, it is a successful opportunist and is found throughout Central Americaand North America east of the Rockies from Costa Rica to southern Ontario (it was also introduced to California in 1910, and now occupies much of the Pacific coast); it seems to be still expanding its range northward. Its ancestors evolved in South America, but were enabled to invade North America in theGreat American Interchange by the formation of the Isthmus of Panama about 3 million years ago. It is often seen near towns, rummaging through garbage cans, or lying by the side of the road, a victim of traffic.

I guess she's not too nocturnal when she has an extra mouth to feed.
