Whenever I was pregnant my cat brought me live things. Otherwise she just displays the dead ones, sometimes neatly placing the head next to the body. The biggest thing she ever brought was an adult squirrel, I was impressed. And she could tell when I was pregnant before I could.
The biggest ewwwwww was my sister's cat who brought in a live mouse once that ran and hid under her sleeping boyfriend (the sister's,that is) on the floor, and we didn't find it till the next day when I suddenly wondered what was under my bare foot and lo and behold,it was the mouse. Have youever tried to lift both feet off the floor and curl all your toes while standing up?
