We had an extremely troubling experience with Petsadena Animal Hospital while preparing our cat for an international move to the EU. I am writing this review so that other pet owners do not make the same mistake we did: relying on this clinic for an international health certificate. I also hope that the clinic will not make the same mistakes again. About one month before our flight, we called Petsadena and confirmed that they provide USDA health certificates for travel to the EU. They recommended bringing our cat for an initial consultation, so we scheduled an appointment well in advance specifically to avoid last-minute problems. During that visit, Dr. Li reviewed our cat and his records and told us that everything was fine. Because our travel date was not yet finalized, we were instructed simply to schedule another appointment within 10 days of departure. We specifically asked whether there was anything else we needed to do in advance, and we were given no warning about any issue with his vaccination history. Once our flight was booked, we returned within 10 days of departure. Despite booking with Dr. Li, we were assigned to a different veterinarian who had never seen our cat and told us that she had never completed a certificate for our destination country. We asked basic questions about USDA endorsement, processing, and when the certificate would be ready. She appeared uncertain about the process. We were then left waiting in the examination room for almost an hour with no updates. Eventually, we were told that there was a lapse of a few days between the expiration of our cat's previous rabies vaccination and his booster. The clinic said it was contacting the USDA and even the vaccine manufacturer to determine whether this might be acceptable. We subsequently confirmed ourselves that the EU rules are clear: when there is a lapse in rabies vaccination, the new vaccination is treated as a primary vaccination, and the animal must wait 21 days before entering the EU. This was not a matter that could be resolved through the vaccine manufacturer or by requesting special clearance. Because our flight was only 10 days away, our cat could no longer travel with us as planned. We accept responsibility for not independently identifying the vaccination lapse earlier. However, we are no experts and this is precisely why we consulted a USDA-accredited veterinary clinic a month in advance, brought all the records, and explicitly asked what needed to be done to prevent last-minute problems. A clinic offering international health certificates should know the fundamental rabies requirements or carefully verify them during the initial consultation. Had we been correctly informed at that appointment, there would have been enough time to revaccinate our cat and complete the 21-day waiting period. Unfortunately, the problems continued. Once we learned that revaccination was necessary, we called Petsadena and asked to have it done immediately. After giving the vaccine, the clinic gave us a rabies certificate showing an expired vaccine. When we questioned whether our cat had been given an expired vaccine, the certificate was taken back and replaced with another version showing a different, valid expiration date. We were told that the vaccine information had not been updated in their system. That whole day is definitely the worst vet experience we ever had... This mistake forced us to rearrange everything: our flights, accommodation in both the US and the EU, and all the other logistics surrounding our move. The resulting expenses were significant. Beyond the financial cost, their repeated mistakes and lack of professionalism caused significant stress during an already difficult move. Based on our experience, I cannot speak much about their general care for animals, but I would not trust or recommend Petsadena Animal Hospital for international travel documentation--or, frankly, for any important documentation.
