Persians are prone to dental issues and the vet suggested a dental diet since I do not really like the idea of anesthesia for teeth cleaning. Science Diet Oral Care and Hills Dental Diet are both full of garbage for ingredients and the kibble is HUGE. Blaze can not eat it. She tried. A couple of them do like it and did eat it, but not the 2 with the most tartar so I need to find something for them and hopefully a better quality. I like the ingredients of the Royal Canin Rx Dental DD27 better but I would have to get it online and can't see the kibble first. Any others that are not full of garbage but that actually work? I am not expecting to find a holistic food like I usually use (Wellness or Natural Balance) but I guess it's a trade off.
