#4 Once in a different climate, animals were forced to adapt to new living conditions.
The size of cats has increased in comparison with their European counterparts, and their coat has become harder and thicker. Wandering days on farms and ranches, near houses and sheds, the ancestors of the American Shorthair were increasingly able to boast of good health. The settlers drew attention to this and soon began to value the "stability" of animals on a par with their excellent rodent extermination skills.
#5 Until the beginning of the 20th century, breeding of cats took place in free conditions.
No one cared about the exterior and purebred pedigree made no attempt to standardize the breed. The ancestors of the "Americans" retained similarities to their British counterparts but differed in a more stretched and athletic physique. In addition, the animals were hardy, intelligent, and fearless, which made them valuable breeding materials. Soon, US breeders realized they needed to keep the breed. This is how the breeding of American Shorthair cats began.
#6 Admirers of these amazing animals were engaged in the acquisition of striking representatives of the breed and the formation of ideal breeding pairs.
This would keep the cats' remarkable appearance and docile nature. In 1904, the CFA organization registered Buster Brown - a direct descendant of the "British" who came to the United States with the colonists. From that moment on, American breeders developed a clear breeding program for cats.
