There are a number of reasons why spaying and neutering pets is not as common in China and Japan as in other countries. One reason is that there is still a relatively strong cultural belief in the importance of breeding pets. In some cases, people may believe that it is their duty to breed their pets in order to preserve a certain breed or to produce offspring that can be sold or traded. Another reason is that there may be a lack of awareness of the benefits of spaying and neutering pets. In some cases, people may simply not be aware of the risks associated with allowing their pets to reproduce, or they may not understand the potential health and behavior benefits of spaying and neutering.
Despite these challenges, there are a number of organizations and individuals working to promote spaying and neutering in China and Japan. These organizations often provide education and resources to pet owners, as well as offering low-cost or free spaying and neutering services. As a result of these efforts, spaying and neutering is becoming increasingly common in China and Japan, and it is likely to continue to become more widespread in the years to come.
