Lone Black Spider

It’s a good thing my mother does not live here. She would be in an uproar. My house is a mess! I was cleaning up the other day, the usual basics; fireplace, dishes, vacuuming, laundry. I even did a little extra and cleaned the cubby hole where my dishwasher is supposed to be (we dont have a dishwasher, its me). I was re-arranging our baby food down there (Rosey cat loves the Gerber 2nd) and low and behold, one rolled right down into my heating duct. I dont have a cover on my heating vent in the kitchen cuz I need to re-size it due to the tile. So basicly, its just this big hole where the heat comes out.
Now I hear it rolling down… then stop. The duct must have turned a corner or something. How the heck do I get that thing outta there….? There is no way I am asking my dad one this one. I know its not broken, and the little jar is sealed tightly, but still, I wonder what will happen with the furnace on and off all winter…..
