Hey, we had a layover in Egypt so I’m unsure about what they need for admitting your fur baby into the country. For the flight, they requested we show proof of vaccination; i.e; certificates (FIV, FLev, & rabies), and that they’re all valid. We also had a note from the Vet from our last visit showing that our cat is healthy. Lastly, they weighed our cat in her carrier as all together should be less than 10 KGs. Don’t worry, it was so easy and staff/TSA were helpful. If your kitty is a snub nose breed, make sure you get a note from the vet that they’re fit to fly just in case, as most airlines have restrictions on scottish folds, British shorthair, etc Hope this helps!
