Maybe some captains will go with "it's not prohibited in the book" and allow you to take whatever you want.

I think most captains fall into the "it's not allowed in the book" crowd and prohibit animals on their plane.

Do you know anything about how importing a pet into HK works?
Do you know what paperwork in required to be signed by the captain? Who would provide that and who would verify that it is correct?
Do you know pets must enter as air cargo at the international airports in Hong Kong? Do you know what this entails regarding where the pet may ride on a cargo plane?
Do you know who needs to be notified in HK and how much advanced notice is required?
Do you know the age and breed restrictions for importing pats into HK?

I just looked these things up and I can tell you that any one of them is a red flag for me as a captain and would be you would be denied a ride immediately.

Asking a captain to do anything this extraordinary is unprofessional. You either haven't been in the industry very long or you have a warped sense of entitlement that would lead you to even bring up such a question. Jumpseat etiquette has always had a very narrow window of acceptable qualifications and behaviors. It is a privilege that comes with responsibilities about which you should become informed. Asking a captain or even another airline to do something as out-of-the-ordinary as importing a pet into a foreign country is so far out of bounds that I have to wonder what experience in your career ever made you think that this was a good idea in the first place.
