Kittens are growing which takes energy.  Below are links to what we feed our kittens.

If these options don't work for you, make sure you find a food that is labeled "kitten" and that the food has been reviewed by The Association of American Feed Control Officials (AAFCO).  Remember that switching foods abruptly can cause diarrhea. Diarrhea is dehydrating and if not managed quickly, can be deadly to kittens. 

I leave dry food out all the time, and feed each kitten a half to a full 3oz can of wet food three times a day. 

I make sure they always have access to clean drinking water. Hydration is so important for kitties!
