Pioneering Feline Disease Models for Translational Research
YiJi Biology, established in 2024 and headquartered in Shanghai, is a pioneering contract research organization (CRO) focused on the development of high-fidelity feline disease models for translational research and therapeutic innovation. As one of the first companies in China to specialize in cat models, we support global pharmaceutical and biotechnology partners with preclinical solutions tailored to companion animal health.
Through our strategic collaboration with the Shanghai Veterinary Research Institute (CAAS), we have built one of China’s most advanced experimental platforms for feline model development. Our services span the full R&D continuum—from model design and validation to in vivo studies, regulatory data generation, and product registration support.
What Sets Us Apart
Expertise-Driven R&D
