Might kittens be different from cats in this regard? I don't really have experience with either, but I imagine kittens may be more tolerating of environment changes.
It really depends on the kitten. If you are ever in the market for one, a visit to your nearest cat/kitten rescue centre will illustrate just how much of a unique personality each kitten has. Some sit on your lap and purr almost instantaneously, some are very nervous, some are playful, some mischievous, some seem to love kids, some don't etc etc.
