I got home in the wee hours of the morning last night, hit the refrigerator for a drink and when I rounded the corned to the LR, there was a very young possum near my cat's dish, frozen in it's tracks staring at me. I wondered why the cat was laying under the dining table like it was, that was odd in itself, but hey, cats do unusual things. It and I froze in our tracks, the cat approached the possum as it took off, and off it trotted to my back door(which I wanted to herd him out of anyway.) That scamp squeezed out through a small rusted out area at the corner of the steel door, a spot I've lived with and worried a little about mice and snakes, but I never thought there was ever going to be a mammal to fit through that tiny space. It was quite the shock on that critter's face when we locked looks upon one another! How the heck it squeezed through that small spot still has me shocked. It was hardly under the size of my cat! martin
