I have always bought the Grennies Bone's for my dog, so I was really excited when they started to make the treats for cats, and were selling them at PetSmart. The flavor of the treats that I bought were the oven roasted chicken flavor. My cat absolutely loves these treats. Whenever I shake the little treat bag she runs to me, and she begs for them. Even if I just give her one, she wants more. Not only do they taste good, but they are really healthy for cats as well. The crunchiness in the cat treats help your cat to get rid of plaque buildup, tartar, and overall make their oral care better in the long run. I also noticed that they helped out with my cats breath as well. After trying out the chicken flavor, I also bought my cat the catnip flavor too. The catnip flavor drove her absolutely crazy and wild for them. She couldn't resist eating them. The Feline Greenies also have a lot of wonderful healthy ingredients in them as well. They have ground flax seed to help with digestion, brewers yeast to keep my cats fur and skin healthy, and taurine to help with eye, brain, and healthy heart function. There are many more great ingredients, like essential vitamins and nutrients. The only ingredient I was not pleased with was the corn gluten meal. It's a cheap filler that they throw into cat food and treats, and it provides no nutritional value to them. It is really hard for cats to digest, and can hurt them in the long run. Over all though, these are great cat treats. My cat loves them, beside the corn gluten they are very healthy, they make my cats fur and skin healthier, as well as helping get rid of tartar, and making her breath smell better. Not to mention she loves the flavors she tried out especially the cat nip. I really want to get her the succulent beef, and the tempting tuna flavors next. If you haven't already tried out the Greenies for you cat you should. They will love you for it, and it will keep your cat strong and healthy.
