I think you are thinking of the phrase  the other way around , which does essentially mean the opposite, but in a specific way. The specific nature of the other way around is that it means that doing what you say in the opposite direction is correct, not necessarily the exact opposite.
You can offer your kitten either dry food, canned food, or both. Be sure to choose food which is designed for kittens. They require a diet which is especially rich in protein, calcium, and other nutrients. Cat food that is for adults is not sufficient.
Solid Food for Kittens. When you begin feeding kittens, offer them small portions of commercial foods that are made exclusively for their young age. If the label doesn't say kitten, it isn't appropriate for their tiny growing bodies, so don't feed it to them. Always make sure that the food is wet and chewy.
