Ex Input:
Bottled like an energy drink, Switch, doesn't contain the things you'd find in other carbonated beverages. There's no sugar, no caffeine, no corn syrup, no preservatives or artificial colors.  Instead, what you get is a refreshing, all-natural, lightly carbonated tangerine-orange drink loaded with Vitamin C. Think of it as orange soda without all the things you don't want. Switch has just the right amount of carbonation to make the beverage refreshing without being filling.  It's a zippy beverage made with real tangerine, apple, and grape juices, and would make a refreshing beverage, lunch, dinner, or snack-time drink.  There was a slight aftertaste that I'm chalking up to either the can or the citrus, but it didn't get in the way of enjoying the drink.  Make the "switch" to Switch.

After trying the Namaste pizza crust I was blown away--Delicous!  Possibly, the best pizza crust I've ever had.  So, I tried their Cheez Pasta thinking it would be great as well.  Big surprise.  It was awful.  I could barely tolerate one bite of it.  I, like one of the other reviewers, will save the pasta but make my own cheese sauce.  The cheese sauce smelled and looked terrible.  Do not waste your money on this product!

My cats aren't usually picky and I've had them on Natural Balance Venison grain free canned and dry food but one still has digestive problems (probably from ten years of eating "junk" kitty food) so I keep trying to find a food that will help to heal him. I tried Felidae and he and one other cat eats it, but the other two don't. I do believe one is extremely picky because he won't eat Halo brand either but loves the Natural Balance and Taste of the Wild grain free options. I hate having to buy so many different brands to please my four cats! Also - this says 95% protein derived from fish - so maybe they are having a distaste for the fish? It's too bad because they do love tuna but it causes the sick one to vomit every time. Oh well, it's a another miss in our family.
