I know vets have contracts with food companies, but these companies also sell wet food which is more expensive so you'd expect vets to try and sell you we food instead. These companies tell you to combine dry and wet food, they have charts to tell you how much of each for your cat. Instead, several vet offices with different contracts all tell me the same, as well as the university hospital, to stick with only dry food so I'm going to stick with that. Wet food isn't great for their teeth and it has too much protein making them fat. My cats are super healthy with a perfect weight. They just need water available at all times so I give them fresh water daily and they have 2 cat fountains.
