I was happy that my samples of Young Again arrived today - I just contacted them at the end of last week! I gave Lucky some, and after a few moments of "WTF is this?" he started chowing down. The packets didn't have serving instructions that I saw, but I thought I remembered someone saying that they get 4.5 Tbsp per day, so I gave him what looked like 2 Tbsp. If I can keep him from turning into a diabetic, I'll be a happy mama indeed. Even better if this stuff will help me finally transition him to all-wet food! It came with a 10% off coupon, too, so I'll probably be ordering some soon.
