The earliest mention of an Asian leopard cat × domestic cross was in 1889, when Harrison Weir wrote of them in Our Cats and All About Them.
However, in 1927, C. Boden Kloss wrote to the magazine Cat Gossip regarding hybrids between wild and domestic cats in Malaya: “I have never heard of hybrids between bengalensis (the Leopard Cat) and domestic cats. One of the wild tribes of the Malay Peninsula has domesticated cats, and I have seen the woman suckling bengalensis kittens, but I do not know whether the latter survive and breed with the others!”
The earliest mention of a confirmed ALC × domestic cross was in 1934, in a Belgian scientific journal., and in 1941, a Japanese cat publication printed an article about one that was kept as a pet.[unreliable source] Jean Mill (née Sugden), the person who was later a great influence on the development of the modern Bengal breed, submitted a term paper for her genetics class at UC Davis on the subject of crossbreeding cats in 1946.
