STLnative is right. Our cat whose name is Cat brought a chipmunk into the house while we were gone. He is mainly an outside cat but comes in when he wants via the doggie door. Well, I kept smelling an odor as I sat at the computer here- not too bad but each day it got worse. Finally I got down and sniffed - really good - bad thing to do. LOLL We searched high and low around the desk here. He either had hidden the chipmunk for later eating or the chipmunk had crawled into my trashcan with the paper shredder on it to hide and there it was - smelling nooooo good. Thanks goodness for the shredded paper to absorb the whatever. LOLLL
