The dark side and light side theory
From the beginning, Ann believed that she had to develop a theory to limit inbreeding and make the gene pool as large as possible.
That’s why she developed the “light side” and the “dark side” theory. This had nothing to do with the colors of the cat.
Ann claimed that the cats from the “light side” had a little longer noses and larger sharp ears, just like a Balinese (half-long-haired cousin of the Siamese). According to her, these cats were beautiful pets and had a slightly better temperament than the “dark side” cats.
The ‘dark side’ cats seemed to be heading in the direction of a Himalayan cat, this is a Persian colour point. The Himalayan cat has a wider head, smaller ears and they have a robust body …
To get the perfect Ragdoll look she said you should breed with a cat from the “light side” and a cat from the “dark side”.
