Information snippet:   During the early 1960's, there was an epidemic of feline leukemia. Around this time, it was discovered that many wild cats had a natural immunity to feline leukemia, as well as other illnesses such as FIV (Feline Immunodeficiency Virus) and feline AIDS. The asian leopard cat was one such cat, and Loyola University started a research program to see if the trait that allowed immunity to such conditions could be bred in or replicated. Dr Willard Centerwall, a professor, was researching the partial immunity ALC's have to feline leukemia, and in his research, done in the late 1970's, he was using the blood taken from ALC/Domestic crosses. The breedings in the Centerwall experiments were done by Gordon Meredith, and Mary Gepford. These F1's (first generation removed from ALC) had no use other than having their blood drawn for testing so homes were needed for them
