I feed my cats Chicken Soup For The Cat Lover's Soul. They are doing awesome on it and you can't beat the smell! Have you tried mixing wet food with some dry? My kitties love it that way. I put about a cup of dry food and half a can of wet food into a dish. I mix it up and add a skin and coat supplement. They are VERY shiny boys!
IAMS is not one of my favorite cat foods, but so many people I know feed it to their cats. They all do well on it, but there is better food out there. Go to your local pet store and ask for some samples of super premium cat food. For example:
Â« Chicken Soup For The Cat Lover's Soul
Â« Solid Gold
Â« Natural Balance
Put a different food into each bowl and label them. See what food get's eaten the most. You will know then what food your cats like best. Slowly change their food, this way it will be less harsh on their stomachs. See how they do on that food, check their stools and see if they are firm, not runny. Watch their energy! When I fed Whiskas, my cats didn't have the energy that they do now. Peppurr is 20 pounds, but he still plays like a kitten!
You will probably see a change in your cats' coats. They will most likely be more shiny and soft. Their stools will be less stinky, which is a bonus!
