Couple of days ago I was working in my basement and I heard some racket...something knocked over. Next thing I know I smell a pong...turn around and there's a squirrel looking at me. Then he turns and runs everywhere looking to get out of the house. Of course he's running into every room (shitting everywhere he goes)....Finally I shoe him upstairs where I opened both the front door and the back door. He finally figured it out and got out. He came in through the (cold) fireplace....right down the chimney. So last night I wanted to have a fire. But I thought, shit, if there are critters up there I don't want them to get hurt. So I just started a small paper fire....kept that going for about 10 minutes just to give them a clue to get away if they were up there. Nothing. So I built a fire, threw a few logs in and it was going fine....nice fire. Then a squirrel dropped right down, directly into the fire. He freaked and convulsed and spazzed all over the place in the fireplace trying to get out. I moved the grate away and he shot out like a rocket, half burned, running all over the house. So once again I ran upstairs to open the doors and this time it didn't take him long to get the hell out. What a crazy stressed out episode! Called a fireplace shop this morning and they said I need a new cap on the chimney opening to prevent the critters from getting in.
