Really. Our cat Joey is an avid mouser. Once I found a whole mouse wedged between two boxes in the basement. He must have been playing with it, and got it stuck where he couldn't get it out. But usually I don't find anything left over. Maybe a tail.
Yeah, it's really an eyeopener to get up thru the night, walk thru a dark house and step on a pile of guts, or a head, especially in summer when your barefooted. Yuck!
