Chausie
A Chausie is a hybrid of the domestic cat Felis catus and Felis chaus, the Jungle Cat. Generations are identified by F1, F2 etc, with F1 being the offspring of the original cat and jungle cat mating. Males in the F1 to F4 generations are usually sterile. The domestic cat breed most widely used for Chausies is the Abyssinian (cat), because they have the same look and active habits as a Jungle Cat but are very much smaller. A Chausie, due to the various sizes of the parents, can weigh between 15 and 30 pounds (when full grown, depending on gender).
