Fantastic product! I raw feed my cats and these vits give me peace of mind on the vitamin-front (I also give them extra taurine, salmon oil & egg yolk). From the moment I get the pot from the cupboard my cats meow like absolute loons incessantly until they get one, it's deafening! ( one cat barely squeaks at all other times ). They crunch them up, then try to steal each other's so I have to referee! Because of their diet they are in tip top condition, but I do think these vits have played a part in that, they've been on then for about 2yrs. Wish I could upload a photo to show you the sheen on their beautifully soft coats.
