I do not understand the comment above that the kibble is "too big" since I took the packages on offer and I had a great time of it. I used to take the royal canin oral care products, because they were the only ones who made them, but I wanted to try these which were on offer and I must say they were much appreciated. They are almost pyramid shaped, but similar in size, like those of the royal canin, so eatable, they just have a stronger smell, but I think I will reorder them
I was tempted to try this product because I was intrigued by the angular shape of the kibble - I could see how it could help combat plaque. Our cats' dental health is OK but I feed several feral cats so I need to take extra care. I was worried when I first saw the kibble as it was rather larger than I expected but there were no sharp edges and the cats weren't fazed, even the smaller ones. Quality seems good and cats munched through it happily!
My cat has mild gingivitis. Since starting him on this food, his gums are less red and his breath doesn't smell. It takes about 3 weeks before you see results so stick with it. The kibble pieces are bigger than regular kibble which encourages chewing but he still manages to swallow a few pieces whole.
I tried this out on my cat with gingivitis. Very effective against that god-awful affliction, the shape of the kibble forces the cat to chew them better. His stool have become much more regular and a little less smelly. Oral Care dry food is very good. I also use Concept for Life for sensitive cats.
