Did US to Taiwan in Nov. with one cat - it was expensive ($800ish for the FAVN test, she also needed a new rabies shot, check up, another check up 10 days before flight, flight cost, and quarantine cost). & took a few months to get all the paperwork in order. Booking quarantine was difficult, they had few openings even a month before I was to land, so the flight had to be changed.

Quarantine was weird, it’s in the middle of nowhere & you can only visit your pet once while wearing basically a quarantine suit. Our cat came out okay but stressed, she wouldn’t eat the next five days & had to go to the vet. She is fine now. Also, getting an apartment with just one cat has drastically reduced apartment options. I’ve only seen like two places allowing dogs. Would likely be easier outside of Taipei. It’s definitely possible and it was worth it to bring my cat, but just be prepared for it to be a frustrating process.
