Years ago, scientists in the USSR set out to discover how quickly a selectively bred animal could start to become domesticated. They started with red foxes and the offspring soon started to have gentler, friendlier personalities and their looks started to change as well. They started turning silver.
After the fall of communism, the scientists lost their funding and started selling offspring of the domesticated foxes as pets in order to further their research. You can buy your own for just under $6,000.
