Its been a week tomorrow since she has been off of her kirkland's healthy weight food (consequently so has our kitty) and on Premium Edge Healthy Weight I. What a HUGE difference!! Both of them have a shine back in their fur. Honey's pot belly is pretty much gone and she is starting to become more active and playful. I just can't believe how much it was affecting her. I don't know if I should report her problems or chalk it up to crappy food. Either way I will be getting a refund on her food from Costco. I think I'll ask the vet what she thinks. Has anyone had a similar experience?
