Due to an alarming decrease in the gene pool diversity of the Havana Brown, the members of the Havana Brown Breed Council, with the blessing of the Board of Directors, approved an out-crossing program for the breed in 1998.

The following is the official CFA Out-Crossing Program rules for the Havana Brown as of 8/28/06.

A Havana Brown cat may be mated with an unregistered domestic shorthair cat (black or blue only), hereafter referred to as F0 or certain colors of Oriental (shorthair only, any color except pointed, cinnamon, or fawn) or Siamese (chocolate point or seal point only). The resulting kittens are known as the F1 generation. The mating of an F1 kitten to a Havana Brown produces a litter that is considered to be Havana Brown, provided the individual kittens meet the color standard for Havana Brown.
