I do not know exaclty what is best for our cats nutritionally, except that the cheaper brands mean less nutrients. Our cats get Iams, sometimes they get the hairball kind, or some others as they are indoor/outdoor. Canned food they oftenget Friskies, but that is only maybe once a day and not all cats eat it, only get about 1/5 of the can each cat lol. My question is for our 5 cats (we cant buy real expensive food) is Iams a good brand? I sadly know more about Horse, cattle and hog nutrition than cats lol (thanks to my animal science class lol). Thanks in advance!
