The trip was very long and we had a lot of problems at the airport. The woman at SAGARPA told us that she won't give us exportation documents for our cats, because we were missing a color copy of our veterinarian id. We offered her, that we could call our veterinarian so she could send a fax with it, but it also wasn't an option! we were told that we have to go back to guadalajara and make the copy or find a new veterinarian in mexico city!!! So, basically we didn't get the permit to take our cats on the airplane and export them to europe. BUT, to make a long story short, the lady who worked as a KLM check-in staff told us that we could take our cats on board without exportation documents, under condition that we take all responsibility for that. We agreed and from that point everything went very smooth. Nobody checked our cats in Amsterdam and in Poland the custom officer turned out to be a cat lover. He said that Blanca was probably the first mexican cat in Poland!
