I have looked at those but I also emailed the japan animal quarantine services and explained they were pet guinea pigs. They told me there is no required quarantine for them but they need a health certificate and a notification form for the ministry labor something and welfare. Everything I read has pointed that I wouldnt be able to take them but then I'm told something else. I was given a contact number so hopefully when I call them tonight I can get a straight answer. Also, I will be trying to fly with Delta since they are very pet friendly and will allow me to bring them as carry on. I'm just not sure how I would be able to bring some timothy hay for my pigs on the plane.
I know its a stretch to bring them but I've had them for almost 4 years now, so I'm at least going to try my best to see if there is anything to get them to come with me. If not I'm going to have to rehome them, which makes me worried since one of my pigs can be a little difficult :/
