Currently, according to the regulations of the China Railway Customer Service Center, cats are not allowed to be brought on high-speed trains as pets. However, the railway department is conducting a questionnaire survey on pet transportation on high-speed trains, which may indicate that there will be relevant policy adjustments in the future, allowing pets to travel on high-speed trains under certain conditions.

Currently, if you need to travel with your pet, you can choose to have it transported by rail or by escort. However, it's important to note that bullet trains and high-speed trains do not support the transport of live animals; they can only be transported by regular train. When processing the transport or escort procedures, you need to prepare the relevant quarantine certificates in advance and ensure that your pet is kept in a designated container.
