If you're getting a baby you could use kitten food, but best to use whatever the breeder/store are using until he is settled and then switch. Just be mindful of fat %.
Most people just give the kibble as is. I personally feel some brands are really hard and my boy struggled and then even refused to eat them ><. You can crush them or grind, but this might make it into dust/crumbs (is what happened when I used a coffee grinder anyways). I now soak my boys food, only way he will eat it. Vet says his teeth are perfectly fine. There's mixed views on whether this is bad for them, but in the wild they wouldn't exactly be eating hard kibble!
I do feed insects daily as well, so he is still having to chew and break down some food!
