Do not buy this product.  You will not be doing your infant any favors.  If at all possible, you should be breastfeeding.  (I know it's not always easy or convenient.)  If you can't then in my opinion the best formula is Earth's Best and even that is disappointing.  Basically, they dry cow's milk and remove all the natural nutrients then "fortify" with synthetic vitamins/minerals.  Pathetic.  Just buy whole organic milk, raw if possible.  There are recipes online to make it closer to human breast milk.  Sorry to be so matter of fact.  I'm losing patience for all these evil corporations capitalizing on the "green" movement.  OH and by the way the second ingredient in this garbage is sugar!!! Good way to start the diabetes/obesity while they're young!

My holistic vet recommended this, along with a few other brands. We tried them all, but my cats prefer this (especially the sardine version). The best part is their coats are so soft and clean and their eyes are so clear. AND (and I don't want to be rude, so I'll say this as delicately as I can) their waste is far less odorous than cats who eat the McDonalds junk found in most stores, which is a definite plus for me! The health benefits are so obvious - I highly recommend Holistic Select!

I have an immense love for pancakes.  I have been on a search for the best pancake mix for about a year. I did not write this review prematurely as I wanted to give the product a fair chance.  I tried it with whole milk.  I tried it with buttermilk. I tried it with blueberries. I tried it without blueberries.  It is by far the WORST mix I have tried thus far.  The flavor is not good, seems like it needs more sugar.  With blueberries, it is very hard to get the pancakes to cook all the way through without overcooking them.  I really am telling you all the hype on this product has got to be from people that either work for the company lol or have never tried another high quality mix.  I honestly would rather eat pancakes from McDonalds.  Don't waste your money!  (Robbys mix is also wayyyyyyyyyy better and I believe it was cheaper). (may be better for waffles...since I'm stuck with two cans I may try that...ugh!)
