Iams is not one of my favorite foods, not because of the ingredients, but because of all the bad things I have heard about the company. Whiskas is not a high quality cat food - it is filled with by products. Iams wet food has great ingredients. Here is a comparison...

Iams Lamb & Rice Wet

Ingredients

Lamb Broth, Lamb, Beef Liver, Chicken Liver, Whitefish, Dried Egg Product, Brewers Rice, Corn Oil, Fish Meal, vitamins and minerals.

Whiskas Lamb & Rice Wet

Ingredients

Sufficient Water for Processing, Poultry By-Products, Poultry Giblets, Chicken, Lamb, Rice, vitamins and minerals.

Notice how Iams uses broth instead of water? And Whiskas doesnt have meat in their top 2 ingredients? Whiskas uses by-products to make up most of the protein in the food, while Iams uses real meat. That means Whiskas would have 90% by-products and only 10% real meat.

Hope this helps!
