I may be confused on what you are asking for. However, if the question is should you feed you kitten, food for a kitten, I would say yes.

It the lady who you are getting them from is using regular cat food see if you can get a little and move her over to the kitten food at gradual rate.

Kitten grow rather rapidly and they need a some extra stuff that help them along.

I found a site that talks about kitten Nutrition:

This is just one site and that there is a lot of information out there.
