Our cat Sugar is a very finicky eater! She will only eat her cat food and usually nothing else. We received the Feline Greenies Dental Treats in Oven Roasted Chicken Flavor for Christmas and I was very skeptical about her even trying them. She loves these treats! I was shocked when she started crunching away and was looking at me for more. They have the extra added benefit of cleaning her teeth, which I love. The shape of the treat and the crunchy texture is supposed to help with tarter buildup (which I will have to gauge over time), and help to make her breath smell fresher due to the added chlorophyll. The treats also have added minerals and vitamins to help her stay healthy, as well as taurine which is an amino acid that is an essential nutrient for cats (low taurine levels can cause eye and heart problems). She is 14 years old this year and our vet says she is as healthy as a young cat. I would definitely recommend these Greenies Feline Dental Treats to anyone with a picky cat like ours – just make sure the bag is somewhere safe or they will be eaten up in one day!
