* Genetics: Hair length in cats is determined by genes. Short hair is usually recessive, meaning two copies of the short hair gene are needed for a cat to have short hair. Long hair is dominant, so even one copy of the long hair gene will result in long hair.
* Possible Scenarios:
* Both parents carry the long hair gene: If both parents carry the long hair gene (even if they have short hair), they can produce kittens with long hair.
* One parent carries the long hair gene: If one parent has the long hair gene and the other has two copies of the short hair gene, all kittens will have short hair but will carry the long hair gene.
* Unexpected Long Hair: The fact that all 6 kittens are long-haired suggests that both parents must have been carrying the long hair gene. This means they likely both have a recessive short hair gene and a dominant long hair gene.
In conclusion: While it's surprising, it's definitely possible for two short-haired cats to produce long-haired kittens if both parents carry the long hair gene.
