First of all, say something more formal!

First, there is a special pet consignment! Spend some money, they will do well! However, I don't recommend this method, because since you say it is not a very valuable cat, there is no need to spend a lot of money on transportation. Honestly, you don't want to hear it. The transportation cost may be more expensive than your cat! This is pet transportation, but it's expensive.

The second way, if you want to put the cat on yourself, you'd better take a bus, because you also said that Dalian is only seven hours' drive from Changchun, so the cat will not be in pain and save a lot of unnecessary trouble!

If the above two methods can't be realized, then talk about how irregular it is!

First of all, the less risky thing is to take the expressway. The inspection is not very strict, and the management of what you bring is not very strict. You can put the cat in a box and punch some holes in it, but it will still feel uncomfortable.

Then, the most unreliable and difficult way is to take the train. If your cat is big, you'd better not use this method. If you have a smaller cat, you can put it in your clothes pocket to avoid security check, but if it is a bigger cat, it is absolutely impossible.

This is all I can think of. I typed it word by word, hoping to help the landlord.

Please don't copy the back! Thank you for your cooperation!
