In vitro fertilization (IVF) is a valuable tool for assessing sperm functionality and for studying the success or failure of gamete interaction in the domestic cat and its wild relatives^1,2. Viable-appearing IVF embryos have been generated in the cat (Felis catus)^3-6, leopard cat (F. bengalensis)⁷, Indian desert cat (F. silvestris)⁸, puma (F. concolor)⁹, tiger (Panthera tigris)^10,11, and cheetah (Acinonyx jubatus)¹². Furthermore, IVF embryos from the domestic cat³, Indian desert cat⁸, and tiger¹⁰ have proven biologically competent as demonstrated by the production of live offspring after embryo transfer.**
