i found a dead mouse under the hallway carpet that was in the path of the airing cupboard door. It had been there a few months (wed be trying to trace the smell for ages) when i picked it up it was absolutly flat just like omething out of a tom and jerry cartoon. i think one of our cats had chased it there and then we kept opening the cupboard door over it ironing it flat!
I go to a indoor bowls centre that has a load of 1200 X 600 fittings at high level in the ceiling, a few of them have dead birds sat on the perspex difusers.
I also came across a dead squirrel in a mains room that had tried to claw it's way out through the door.
