My cats like Iams , but I keep hearing that they have changed the Formula too much. So I got the Eukanuba to give them more protein. But I thonk that most of the Premium brands are the same. Moose swears by the Weight control Nutro Complete Care , some like the Pro plan indoor Cat , some Thge Royal Canin indoor Cat ansd some The Science Diet Chicken and Rice.And they mostly all like Fancy Feast and Whiskas Temptations!
