i don't know how your trip went, but i would NEVER take a cat on a trip, most cats do not appreciate it and do not like "changes of scenery" or loud noises that can damage their ears on an airplane. your cat is an animal and a cat is the most sensitive animal when it comes to horrible loud noises that can terrorize them and cause heart attacks. and if put in a cage in flight can bash their nose and teeth trying to get out once the noise starts.
you go on the flight and leave the cat in his/her comfortable surroundings. they are not dolls, and they are not dogs. they are animals and they do not like to fly or go on vacation trips with us, no matter how much we want them to.
