THis product (which i am not allowed to return) has ingrediants of salt, spices, hydrolysed soy protein, that last item is the common industry con for adding msg to your food. Every soup on your grocers shelf contains msg, but, i digress. So, the third ingrediant is a form of MSG, further down the ingrediant list is proudly displayed ... Monosodium Gludamate, ...MSG. This does not add spice to your food, it stimulats your tongue into feeling that the food tastes good, when IT DOES NOT. MSG can make dogfood taste like hamburger. anyone who thinks this is making their food taste cajun may be serving ALPO.  Tones and Durkee (sp) do not contain MSG, I prefer Tones!  I have 8 eight ounce cans of this stuff.. would anybody like to buy some hamburger from me?

Many reports are coming out about how chocolate is actually good for you, so eat more!  This is the perfect chocolate to do that with.  The varying levels of cocoa are perfect to help adjust your taste buds to eating dark, dark chocolate. It's not an easy transition for a milk/semi-sweet kinda gal, but this chocolate is affordable and so tasty.  I also like that I can just have one (as they are individually wrapped), and choose my %.

I honestly cannot say that I saw any difference whatsoever in this variety compared to Friskies regular sliced beef version.  Actually, my cat preferred the regular Friskies over this one.  He's not really all that jazzed over these Fancy Feast varieties anyway, so if you're going to buy this one or the chicken, save your money and buy the regular Friskies versions.  They seem to taste better to the cat and it saves you money.  I've never had a cat that ever got too thrilled over this variety over the years so I guess I'll get the special ones instead.
