Can pets and cats immigrate?

I think so, but it's very troublesome. First of all, we need to implant lenses, do n physical examinations, go through many procedures and spend a lot of money. Finally, I have to buy an aviation cage and a seat alone. It will take a long time to fly to America, and cats will be miserable. Last time, my sister insisted on immigrating a Beijing Ba dog. As a result, when she got off the plane (she went to Canada), the dog threw up in a big mess and became ill in a few days. Therefore, I don't advise you to immigrate to pet cats.
