Hello, i was feeding my 9 months old kitten nulo chicken but she got bored with it. I was giving her nutrience - chicken, turkey and herring after that, she slept throughout the day more than usual. So i shifted to instrinct with real chicken but she doesn't like it seems. Im confused between orijen ( kitten or chicken turkey all stage) or GO! (Chicken turkey and lamb) or crave or should i stick with instrinct. I didn't find any good or bad reviews regarding these companies. Which is more nutrient and better for my cat's health? As i will be sticking with that brand from now. Only will change the flavor. Is magnesium bad for cats? Like 0.1%-.9%? Thanks
