Travelling can be a stressful experience for human beings and it is probably equally so for cats, although for different reasons. While your cat is not going to be worried about arriving at its destination on time it will have been plucked from its familiar territory, put in to a container and subjected to an array of strange sights, sounds and smells. A frightened animal is likely to panic and so care has to be taken to make sure it arrives safe and well at its destination.
