Mostly what we see are squished squirrels and sometimes birds,usually pigeons. The latter doesn't upset me that much, since we are overrun with pigeons and I remember having hordes of them crapping all over my air conditioner. I love all animals so it upsets me a bit. I hate seeing squished squirrels or chipmunks, though. I sometimes put on a big act pretending to bawl like a kid, "waaaaa, a squished squirrel,we have to go back and bury him!"
