Three out of our four eat blue buffalo spa select. Tuna eats royal canin s/o as prescribed by his vet.

I usually shop at Petsmart because it is most convinent to me and this was by far the best food avaliable there. I really like the ingredients, these are the first 5.
Deboned Chicken, Chicken Meal, Whole Ground Brown Rice, Fish Meal, Whole Ground Barley

I've noticed that Nutro is very popular here, these are the first 5 ingredients on their indoor formula.

Chicken Meal, Ground Rice, Corn Gluten Meal, Rice Flour, Poultry Fat

I much prefer the blue buffalo because it has more sources of protien and does not have corn listed in the top 5.

A lot of brands that make high quality dog kibble also make versions for cats as well such as Wellness, Wysong, Felidae and many others. Just like you would with dog food check the ingredients. If you wouldn't want to eat what is in the food, then odds are it isn't good for your kitty!
