Max Nutro is what I tried on my cats. They didn't care for it.

I find Blue "Wilderness" works best for my cats. You've really got to read the labels for ingredients. Wilderness cat food is high in protein and first ingredient on list is CHICKEN. Not Chicken Meal By-Product Meal. All natural ingreients. My cats love it and don't eat as much. A big bag is $33. One bag with 6 cats lasts me a month. I also give them canned as a treat.

I've noticed my cats coats are shinier and healthier. RB MooShoo lost weight on it.
