Just wanted to let everyone know what worked for my ferret Buster in gainning weight. He dropped over a pound in a half in one months time span ( going from over 3 pounds to just under a pound in a half) and I tried everything. The vet suggested I try Deliver 2.0 (you can order it from any pharamacy) and now Buster Baby is on his way back to almost tipping the scale at 2 pounds (he used to weigh 3 but we are working on it). You can get a case of the Deliver for about $20.00 and I mix this in with the Duck Soup. I mix the Deliver in the Soup mix until it becomes thinner..since Buster likes it that way. The vet recommended Deliver 2.0 because it contains more calories then any of the other high calorie drinks on the market. Good Luck!
