the baby opossum

ok, so had i my wits about me...i would have run to get the camera when i was preparing to feed the pest this morning.....and a baby opossum was in the catfood bag......nope...i shrieked.......and plucked the entire 25 pound bag out of the pantry and raced it outside.....and watched in relief when the animal raced off toward the bushes.......the dogs were no where in sight, thankfully....and while i know that opossum's are not dangerous....well....i think i know that.......it still begs the question of how it got there.....and are there more of the family lurking about......omg.......
