In 2009, with her love for cats' quiet and independent personality, Dr. Wang Hui established the first Najiya Animal Hospital in Beijing, which is also the first animal hospital in Beijing with cats as the main treatment object. At present, Najiya has a total of 9 stores across the country, covering Beijing, Zhengzhou and Chengdu.

In 2017, Nagya established the Feline Disease Research Center, which is committed to the clinical treatment and drug development of feline diseases, and Nagia is also the only authorized clinical trial animal hospital in China for the feline infectious peritonitis drug GC376 American Scientific Research Center, and the Nagya Cat Specialist Boya Branch located at No. 1 Longxiang Road, Haidian District is the first animal hospital in Beijing that only treats cats. According to the habits and characteristics of cats, the hospital has formulated the most suitable diagnosis and treatment environment and service process for cats, and provides professional and meticulous feline treatment services for cat pet owners.

The décor of Nagiya Boya Branch is a simple Nordic style, with light blue and beige as the main colors of the decoration, which creates a warm and refreshing atmosphere for the hospital, effectively reducing the tension and discomfort of pet owners and pets. The hospital is also specially equipped with a room for cats to entertain and rest, so that cats can be moderately relaxed while waiting for treatment.

In addition to medical services, Nagia has also set up an adoption center and a "cat research institute". Nakia Adoption Center is a "halfway home" for stray cats, providing cat adoption services for the majority of caring people. The hospital will conduct a comprehensive and detailed examination of the stray cats to be adopted to ensure the health of each cat to be adopted and dispel the adopters' concerns about the health and safety of stray cats. The "Cat Research Institute" is an accurate distribution platform for cat health knowledge information carefully launched by Najiya, which can provide pet owners with relevant knowledge on cat care, medical treatment and feeding according to the needs of cats, and improve the ability of pet owners to take care of cats.

Although Nakia is known for its feline specialty, its branches are comprehensive general animal hospitals, covering the medical and surgical needs of companion animals. Located in Chaoyang District, Baiziwan South 2nd Road, Najiya Lecheng Diagnosis and Treatment Center is with its excellent diagnosis and treatment environment, first-class equipment and high-quality customer experience, in 2015 and 2016 won the title of China's Top 100 Pet Hospitals for two consecutive years.
