I had friend as a kid who's hippy brother had one as a pet. They never really become "tame".
I was visiting Montreal for a long weekend in 1985 ($29 one way fares via People Express). While walking though Old Montreal, a fashionably dressed youngish woman had a young ocelot on a leash on the sidewalk. As I walked by, the kitten attacked my achilles tendon on the back of my foot, like any wild animal trying to take down prey. I agree, animal instinct overrides 'tame' every time.
