Don't worry, you are going to be a GREAT meowmie to your new kitten. You don't even have her yet and you are so concerned about what to feed her, what litter to use, and so on and so on.
Mina is going to have so much love and care from you.
Don't worry so much about it, just go with the flow and have fun with your new kitten.
You have gotten some great advice, so you have nothing to worry about.
You know if you have any questions, even if you think yourself it might be a silly one, you can always come on here and ask away, because no question or worry is silly to us.
