Athena's allergies are pretty bad and I'm on the verge of switching her since she's due for a new one soon anyways and she's on Fromm Gold now which is not grain free and oatmeal is the 5-6 ingredient I believe so I'm hoping if we switch her again it will help some. I know Zignature is great but it is a little on the pricier side and it's not in any stores near us so I'd have to order online so I think I'm going to stick with Fromm but here's where the big question is: Starches. I know she should not be getting grains, but I don't remember about starches. Mainly potatoes. Because of her allergies are starches okay or should I be looking for something without starches as well?
