I feed my Scooter Fromm grain free Surf and Turf, TOTW and had tried EVO with him. Some times I'll throw a bag of Natural Balance in if I need more rotation. He loves the Fromm and TOTW. So I trade off between the two brands and rotate his protein. I also feed him wet food such as Wellness, EVO, Tiki Cat and I just discovered the Wyson brand as you can buy that for the cat or the dog. Scooter and Leah love the Rabbit formula. I also give high quality treats to him. He loves the hard treats from EVO. I order those on line. He often gets "real" fish if I'm making fish or small cuts of meat, like chicken.
I learned the hard way with my last cat. I feed him SD before I knew better and he was a miserable cat. Always throwing up and then diabetes. At the end of his life I had started to switch to good food and I think that is what has "saved" Scooter. Scooter is 15 and is not over weight, doesn't have health problems and acts like he is a kitten.
I would say there are as many good cat foods out there as there are dog foods.
Marty is cute, he could be Scooters brother
