I have been using this product for a little over four years and my three cats are plaque free. They never took issue with the taste which I sprinkle on their food daily. One of my kitties is nearly 15 years old, and the other two brother and sister kitties are nearly 14 years old. Recently my vet told me that if he didn't know these cats' ages from their records, that he would estimate their ages at half that or less. To be honest, I attribute their excellent health in part to Mad About Organics All Natural Dog & Cat Plaque Remover Dental Food Additive.I started using this product after one of the kitties, who at the time was a little over ten years old, had a $350.00 dental bill due to a very bad plaque build up and resultant tooth decay. She consequently had to have a couple of molars removed. I felt like so bad about her teeth loss and I had two other kitties that had plaque build up as well. So I was looking at a minimum bill of a couple of hundred dollars for each of the other two (their plaque problem was not as bad)So I started looking for an alternative treatment to remove and prevent plaque. None of my cats would put up with having their teeth brushed - so that attempt ran another $50.00 or so dollar experiment that failed.Then I stumbled across the Mad About Organics Oral Care powder on Amazon, which had very good reviews. I eat all organic and feed my pets all organic - so the fact that this product is organic is something I particularly appreciate. But I was frankly a little skeptical. However, after reading the reviews (which were all mostly very high ratings), I decided it was worth the price to see if it worked.I was amazed that the other two kitties plaque problems cleared up within a few months, and ever since then none of the three cats have any plaque at all. It did take awhile but was definitely worth the wait. I don't think anesthesia is ever a good idea if it is possible to avoid it as it is known to be more dangerous than most surgery - for humans or pets.For those who think this product is expensive, you use an amazingly small amount (which is based on weight) once a day. A small spoon comes with the product and I would say that spoon is less than or equal to an 1/8 of a teaspoon. Based on my cats weight, two kitties get one scoop and the larger kitty gets one and a half scoops per day. A 4 ounce jar lasts about a month and a half for my three cats. So compared to a vet bill to put your pet under and clean their teeth and perhaps have to remove some teeth - well, do the math and consider the inherent risks.So I highly recommend this product, and have recommended it to several friends who have also had excellent results with their cats and or dogs. Just remember that it may take awhile - probably dependent upon how much and how old the plaque build up is. If your dog or cat has years of plaque build up it may be best to have your vet clean their teeth as good oral health definitely supports overall good health - but afterwards, this product would be an excellent preventative method to keep your pets teeth plaque free!
