Hiya, I just took a kitten from my friend and I have no idea what the best way to feed the kitten is?

I get all sorts of ideas from people and I just want to feed him the right way as I do not want to overfeed or underfeed him.

Also the maintenance of a kitten? I think I bought the basics but I need to know what other things I need to look out for? Like worming, fleas and how often I should get her checked at the vets??

Please let me know. Many Thanks
