What's the most stressful part of travelling with your pet?

Hey everyone, I built PetPass because I travel frequently with my cat around Europe and kept forgetting documents before flights. Vaccination dates, health certificates, airline rules were scattered everywhere and I was always second-guessing myself.

So I built a free tool during my vacation that stores everything in one place and gives an AI overview of what to expect for your specific trip. Not an official passport, just a way to stay organised.

Curious, what's the most stressful part of travelling with your pet? Documents, airline rules, finding pet-friendly accommodation, or something else entirely? Would love to know what to focus on next.
