We used to have two male cats adopted together as kittens from the local humane society. One was timid and mostly stayed home. The other preferred to be outside. They loved each other, though, and the indoor cat would wait at the top of the stairs for the other to come home.

The bolder cat was hit by a car one morning and died. His adoptive brother never fully gave up waiting for him at the top of the stairs. As far as he knew his brother just hadn't come home yet. It was quite sad. It wasn't long after that that he went outside for the last time and never came back.
