What I have done from the start when I introduce kittens to dry food is mix it. I use Science Diet, Iams, Eukanuba, and Royal Canin kitten dry. So when they leave the parents can use all or some of the dry foods mix. I have mixed dry food with my adults for over 8 years. If one is out of stock it will not upset their stomachs if it is not there. This has seemed to work for me very well. And none of the cats have ever turned their nose up at it.
