Based on the development history that the modern medicine and laboratory animal science have long been hindered by animal welfare groups and animal-rights activists in Western countries, and considering the relevant circumstance in China, the author appeals and recommends that the laboratory animal practitioners and biomedical researchers, the scientific community in China should recognize and identify the boundaries of our professional activities. Firstly, do not participate in the activity related to so called “World (Lab) Animal Day” that is said in some Chinese websites, to originate from NAVS, an antivivisection society Ltd. , London. Secondly, do not participate in the activity related to so called “animal memorial stone” that was originated in Japan. These movements have nothing to do with biomedicine and laboratory animal sciences, and fundamentally are antiscientific and are incompatible to traditional Chinese culture. Thirdly, distinguish the standpoints of laboratory animal science from various viewpoints of animal welfare/ rights activists, promote scientific management of the institutional animal care and use for better supporting biomedical research in China.
