Well you've hit on the old nature/nurture question there jseal....certainly it has been proven with cats that their 'friendliness' has genetic links as studies have proven that kittens fathered by a 'people-friendly' tom usually inherit this trait, despite the fact that tom cats rarely hang around to nurture and raise their offspring.

As for other aspects of personality, who can say? From a personal point of view, the cats I've had have always been raised with litter mates or another kitten, which is something you'd not be able to recreate were you to clone the animal. I imagine a clone of one of mine would have a very different relationship with the surviving older cat than it would have if they'd been raised together from kittens.
