The protein percentage in Ensure is great. The sugar percentage is not. When you mix one cup of sugar with one cup of meat, you've got 50% protein & 50% sugar. Which may sound condescending, but the simple truth is, that a lot of fairly intelligent people get confused when percentages enter the nutrition discussion. Ensure's got a lot of really good ingredients... but by the time you mix it with enough other stuff to bring down the sugar percentage... YOU'VE ALSO REDUCED THE PERCENTAGE OF THE OTHER GOOD STUFF to trace amounts! You are essentially wasting money. Instead of Ensure, use something that has the good stuff without the sugar. (You might try Deliver 2.0. You may have to have your pharmacy order it for you.) On the side of being safe rather than sorry, I also tell people not to put Ferretone on kibble. Many people commonly "add to" the kibble in a free feed bowl, and dump the crumbs only once a week or two weeks, even... Busy lives... refills on the run... we're only human, Supermoms & Superdads are rare and don't last long. Ferretone soaking into kibble crumbs in the bottom of the bowl can get rancid without being noticed. Debi Christy Ferrets First Foster Home [Posted in FML issue 3154]
