I worked at an independently owned pet store for 2 and a half years and at least at my store, we would always get comments about how much lower our prices were than Petco and Petsmart. Also they will usually price match for you, unless its a sale item or online price. Independent stores can not usually compete with online pricing, but they try their best.
I’m not sure about Authority or Simply Nourish, but I know with Purina I can call them and they will tell me exactly how much fiber is in the formula I’m asking about. The Pro Plan formula I use reports 3% MAX fiber, but when I called and asked how much the actual true value was it was much lower (dry matter fiber was 1.6%). It is possible that she may need a little more fiber in her diet yes. However, if you chose to go with a food that reports the MAX fiber high like 6% I would not also add pumpkin as it could cause too loose of stool.
Also I would highly encourage you to contact Purina Pro Plan directly. Their customer service is beyond wonderful and I think they will help put your mind at ease.
