The Door Bell Rings and ....

The door bell rings and I ask, "Who is it?"  There is no answer.  I say again, "Who is it?"  Again there is no answer.  I go to my window to look outside and there stands the neighbor cat crying. "I am hungry, hungry and hungry more."  I was amazed, is it possible that these poor helpless creatures could ring my door bell and tell me they are hungry? 

Well of course I had to feed them.  I thought I had heard of everything, but now I know this tops the cake.
