When I first started caring for our inherited cat colony, I was a novice. I did some reading and discovered the type of protein in dry cat food is not as good as the protein in wet cat food. Some online sites recommend NOT including dry cat food along with the wet for many reasons, including that it can make them fatter or contribute to diabetes later. But I think they need it for keeping the plaque off their teeth, so I offer them both. The ones who favor the dry food seem to me to have better teeth conditions.
