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.
While waiting for the shelter to have room for your kittens you should: Provide proper nourishment. Kittens 5 weeks old can be started on wet kitten food â sometimes adding a kitten replacer (available at feed/pet stores and veterinarians offices) to the wet food can help a kitten who is a little undernourished. Kittens 6 weeks and older can eat wet or dry kitten food.
