Pedialyte is better for hammy than the Ensure. Just fill the water bottle with it. Also try giving your hammy a bit of scrambled egg (no salt or spices on it), oatmeal, dry or cooked and chicken baby food...make sure there are no onions or garlic in it. I use Gerber Chicken and Gravy. some cooked pasta goes over well. I like ditalini since it fits hammy paws so well. Hope the little one feels better soon.
