Can anyone tell me why?

I've never seen Moon get in a carrier so fast as when I open the door on the floor of the vets office. At home, it's like trying to put a rabid octupus in that thing.

My vet has an explanation for that. He said the carrier is "like a tunnel to home." They are oh so glad to get in when they are at the evil white coats office because they know that home is the next stop.
