My two cats, brother Emmitt & sister Moon confuse everybody but my son & me. His two kittens, sisters Baby and Slick don't look alike at all. My mama dog CheekyBitch and her son Thunder both look like black and white border collies and my daddy dog Badger and his daughter CollerFlower (don't ask) both look like blue merl (sp?) aussies. CollerFlower was from mama and daddy's first litter and Thunder was from their second AND LAST litter. All get along beautifully - cats and dogs. Laurie
