Congratulations on your new kitten!
I absolutely ADORE Himalayans and Persians, I have two Persians myself and they are such incredible breeds. As Evince said, wet is always best. What I've done is fed wet as the majority of their diet, and supplemented one meal a day with a high-end, grain-free kibble - right now I'm feeding Orijen which I highly recommend.
A tip - keep their chin hairs trimmed and their bum hair trimmed. This will prevent food (especially wet food) from being stuck in their little "beard", and the bum trim keeps it from getting any poo stuck which happens frequently with long-haired cats.
Also... if I could give you one more tip not related to food, it would be to get TWO kittens instead of one. You'd be amazed at how beneficial it is for them. At first, I only got one Persian kitten (my Ellie). She was a doll, but was ornery, acted out, scratched us, and was beyond bored even with playtime. But when we got our second Persian, Tootsie, everything changed. Since Ellie actually had a feline friend to play with, she became an absolute angel toward us and things have been unimaginably perfect since then. If they're hyper, they play with each other and wear each other out instead of acting out toward us. And they're completely inseparable - they cuddle together, play together, eat together, sleep together, groom eachother, kill bugs together (lol) etc. It really is great for a kitten to have a playmate!
I swear by it after my experience.
