Dry/Wet food help

Good morning all.....I am looking to better my kitties health and change up their food choices. I have 2 kit's a 2 yr old tabby (12 lbs) and a 1 yr old tabby (9 lbs). The older one is a food hog, she gobbles u p way more then her fair share, and usually pushes the little one out of the way to get her wet food.

We currently feed 1 1/2 cups dry Purina Cat Chow and 1 can of pro plan for the 2 of them.

I'm looking mostly for suggestions on what dry to change to. Price is no object. We tried the Purina Natural but it disagreed with one of them. Any thoughts or suggestions of what would be a more healthier choice for them.

Where do you get the pro plan ??

I get the pro plan wet at petco
