What in the world???

Elsie and I were out in the garden and I heard/saw something move under the bamboo. I thought it was a cat at first but then it somehow crawled up the plastic fence and until it turned around I still couldn't tell what the heck it was....

Look at mama opossum with all those babies hanging off her! I don't know how she climbed that slick plastic fence but she did it...with all those little ones attached!
