I looked out my window the other day to see my neighbors holding cameras, looking up at my house. A vulture was perched on my roof! My cat must have smelled him, because he climbed up after it! I was afraid it would carry my cat off, until my neighbor reminded me that vultures only eat dead meat, they don't kill it themselves.
If I was superstitious, I would wonder if this was some kind of omen. I just wish he could have hung around until Halloween. :)
