I'm not sure if this is what you are looking for, but it this site has a few cool things on it.
i looked at the pics of jojo, and i am not convinced that you are going to achieve that look with out the help of fake lashes. i'd suggest the darkest black liquid eyeliner that you can find, i know cover girl makes some good ones, but it can get pricey, if you want to stay on the cheap side of it i'd say a dark smooth gliding pencil eyeliner and a couple of heavy coats of a dark mascara would do the job, though it would be as crisp of a line that you'd get with a liquid... as for the cat eye affect, your just gonna have to spend an hour with a bag of cotton balls, and an eye make-up remover, a steady hand and a ton of practice to get that look. also, like with a hairstyle, just cuz it looks good on her won't mean that it'll look good on you. a dark color might make your skin look washed out and pale, too much on the crease of the eye and not enough at the corner of the eye might make you look less Sexa, and more goth.
