Lilly: Hee hee, no way! What's important is that you care about what your cats eat, and you are trying.
If PetSmart is your only option, and remember on a higher brand of food, typically your cat will eat less, which makes the food last longer, so it's not really more expensive in all cases for a better brand. I struggled for years between trying to feed what was best and what I could actually afford.
I work inside of a PetSmart, but not for them, and I know a lot of people who do work for them from all over, the PetSmart workers go by what they are told, and by what sells the most, Nutro sells A LOT, but it is not the best, I would do very little listening to PetSmart employee's, they are not nutritionist, they are not trained to know why one food is better then the other. No I am not a nutritionist, yet, but I have done many years of studying, enough to know that when a PetSmart employee tells a customer to stay away from foods that have corn in them, and then turns around to tell them to buy Nutro (which has corn) that they are blind idiots, lol.
So, from PetSmart, the best selection there would be (in no real order)...
Authority - Lamb & Rice
Blue
Nutro Max - Kitten
Nutro Max - Adult (with Salmon Meal only)
Nutro Natural Choice - Kitten
Pro Plan - Adult Beef & Rice
Pro Plan - Adult Chicken & Rice
Pro Plan - Adult Salmon & Rice
Pro Plan - Turkey & Barley
Pro Plan - Kitten
Royal Canin - Babycat 34
Royal Canin - Siamese 38
Royal Canin - Kitten 34
Royal Canin - Special 33
Royal Canin - Outdoor 30
Hopefully among these 5 brands your cats will find something tasty and that you can afford, yes you can continue to feed this bag of nutro there is nothing wrong with that, you can buy another food and slowly start to mix it in with the other, however you want to do it.
