A childhood belief about cats and dogs

I remember my aunt had two identically marked cats, Abadon and Adolph. I asked, what kind of a cat is Adolph. And she said he's a male cat. I asked about Abadon and she said she is Adolph's mother. I knew there were boys and men and fathers and girls and women and mothers, but didn't know there were males and females. So of course I heard "mail cat".

So I thought long and hard about how this cat could be a mail cat. I figured that's why she let him out in the morning because he had a lot to do during the day - delivering the mail, helping with the mail and such.
