Abstract: Since the late 19th century, Cats (feliscatus) has been used for scientific research. Now, it is widely applied in various fields of medicine. In addition, cats are gaining more and more attention as animal models of human genetic and infectious diseases. The quality of cats (especially genetic quality) has a significant impact on the accuracy, reproducibility, and scientificity of the findings. It is comparatively vital to carry out genetic quality testing on a regular basis to avoid the deterioration of germplasm, genetic drift and the error of experimental result . With the advent of biochemical markers and DNA molecular markers, a more simple and reliable method for understanding the genetic structure of cats has been provided. In this paper, the current research status and existing problems of biochemical markers and DNA molecular markers in the study of cat genetic structure and polymorphism are discussed.
