Susan, the woman I got her from had already taken mum and her kittens on a 600 km journey by the time I got her. I just continued, taking her to the grocery store to start with. Then to visit with friends. The long journeys were interesting, and she never got lost. I don't know what she did once I let her out in the mornings, and I'd get back from a conference and she'd be waiting. It made things so much easier when heading away on holiday, we didn't have to get anyone to look after her. I don't know how true it is, I heard the Dalai Lama carries a cat with him, hidden in his robes when travelling.
A kitten I had earlier, was taken by bus, train, boat, and aircraft. The journey by plane was interesting. I had given her some water at the airport in Dunedin after traveling from Auckland. When I got back on the plane, she meowed, and the woman ahead of me asked the hostess had she heard a cat? The hostess said we don't allow cats on planes, and didn't say anything to me so I didn't enlighten her. My kitten was six weeks old, tiny, and I carried her in a paper bag with a pillow case in the bottom, and she slept most of the way.
