Elyse, you can also call different pet stores because sometimes the store locators on the websites give some false information. Some of the stores may carry the brand but not the exact product that you're looking for. It's happened to me a few times. Now I just call before I drive any where.

If you still want Cassie on a grain free diet that has lower protein, then you might want to try Merrick's Before Grain dry food. I currently feed all of my cats this dry food in the Chicken and Salmon flavors. I buy it from Pet Club but I know you don't have one in your location. Petco also sells it. I don't think that Petsmart does. Merrick also makes canned Before Grain but most of my cats didn't like it so I don't buy it any more. I actually had to return most of it. The only canned food that I found to be palatable to all of my cats has been Wellness grain free. They have many different flavors like Chicken, Chicken & Herring, Turkey, Turkey & Salmon, Beef & Chicken, and Beef & Salmon and all of these are grain free. Since I have so many cats now, I buy the large cans of it and I found that An Jan Feed & Supply store sells it for the best price. They only carry the small cans at Pet Club. Petco and Petsmart also have it but it's more expensive. If you do have a feed store near you, I'd call them to see what kinds of better quality cat foods that they carry because they will usually be less expensive than the big chain stores. I was also told that cats who are used to eating the cheaper grocery store canned food seemed to adapt easier to the Wellness canned food. Here's their website: http://www.wellnesspetfood.com/index.aspx. Good luck.
