The Florida White rabbit was developed during the 1960s by Orville Miliken, a judge and breeder based in Florida who set out to create a small, all-white rabbit optimized for both laboratory use and the show table. Miliken recognized that the existing compact white breeds available at the time did not fully satisfy either the research community, which needed a uniform, manageable animal with consistent physiological characteristics, or the show fancy, which valued a well-proportioned, typey rabbit with clean white fur and ruby-red eyes. His breeding program sought to merge these two worlds by producing a rabbit that was small enough for efficient laboratory housing yet robust and well-muscled enough to compete seriously at American Rabbit Breeders Association sanctioned shows.
Miliken's foundation stock drew primarily from Dutch rabbits, Polish rabbits, and New Zealand Whites. The Dutch contributed compact body structure and a calm disposition, while the Polish brought refinement of bone and the diminutive frame that Miliken wanted as a starting point. New Zealand Whites, already the dominant laboratory breed at the time, contributed their albino coloring, dense flesh, and the physiological uniformity that research institutions demanded. The challenge was blending these three very different breed types into a cohesive new variety that expressed the best qualities of each without the faults that would disqualify it in either a laboratory setting or on a show table.
The breeding program extended over several years of careful selection. Miliken culled aggressively for type, selecting only those offspring that demonstrated the compact, well-rounded body he envisioned alongside the pure white coat and bright ruby eyes that would become the breed's hallmarks. He paid particular attention to bone density and muscle development, wanting a rabbit that would dress out with a favorable meat-to-bone ratio despite its small size. Temperament was another critical selection criterion, as both laboratory handlers and pet owners needed a rabbit that was docile, easy to manage, and unlikely to injure itself or its handlers through nervous behavior.
By the late 1960s, Miliken had stabilized the breed to the point where it was breeding true for type, color, and temperament across multiple generations. The consistency of the offspring demonstrated that the genetic foundation was sound and that the Florida White was no longer merely a crossbred project but a genuine breed with its own identity. Miliken began exhibiting his rabbits at regional shows in Florida, where the clean lines and compact proportions of the new breed attracted attention from judges and fellow breeders who recognized the potential for a small white rabbit that could fill multiple roles in the American rabbit landscape.
