OK, got it, you mean the white band across the chest on the typical hamster coat. Stripes to me suggested something running the length of the body, like in a chipmunk (or skunk!), If you look at it sideways, body of the typical hamster colour is solid with the markings on the chest only, my first one as a kid looked like that. The hamster my daughter had was a solid creamy colour, no other markings at all. Thanks for solving the mystery of the striped hamsters!
