To check in pet cats by train, which department does laohekou city need to apply for animal quarantine certificate, and what materials does it need?

First of all. Your cat needs vaccination. I have proof of immunity. Then go to the local animal quarantine office to get the quarantine certificate. Then you can go to the railway freight department for consignment. I suggest you call the railway department. Ask about the specific links, because every region is different. If you are from Shenyang. This is the process.
