Have you tried Chewy for meds and food? They were helpful to me when I had a chronically ill cat with a special diet. When he died they had me donate the unopened bag that came within days of his death to a shelter in memory of him. It was a $150 bag. I will always be thankful to them for this. They also are FAST, sometimes arriving 24 hours after the order is placed. I don't even know how they do that. They have awesome customer service if things don't arrive or aren't right. I need to switch my flea meds to them.
