Grain free cat food This was the first time I have tried your brand of food. My cats absolutely love it. It's almost like a treat to them. Their hair feels healthier and softer. I will continue to use this brand of food, also trying other flavors of items of this brand. I would defiantly recommend this food to anyone who asks about it. This will be my choice from now on. Thank you so much for your hard working and making great products. August 19, 2013
Great food! I have two cats. One is extremely picky and the other is not picky at all. Both of them absolutely love this food! Even the picky one ate and enjoyed it right away! August 15, 2013
My Cats Like It. I have three cats and they all enjoy eating Science Diet. One bag lasts me over a month with three cats eating twice a day. They digest the food well and don't get upset tummies. July 12, 2013
This product keeps my cats in great shape. I've used this product for years and my barn cats stay in great shape and are always very healthy. They are very active, their coat is always shiny, and are eager to eat their food. This is the only food they've had since they graduated from Science Diet Kitten. February 27, 2014
its the best my cat loves it excellent the best cat food your cat can eat my cat loves it February 4, 2014
The perfect balance for our cats health and fitness. The dry food is the cat's main meal. We use the treats & wet food as a special in the afternoon. February 4, 2014
a little pricey but it is keeping my cat healthy My male cat was just over a year old and was blocked completely. Almost had to put him down. Able to get him unblocked, and switched to this food bladder health C/D. He enjoys his new food and has not had any issues since. My only gripe is the cost, about double from what I was spending on Kirkland brand adult cat food. That is minus the vet bills of course from having to get him unblocked. January 15, 2014
this is a good product Our 6 cats all eat the same cat food and this is one in which they really like the taste of the food and I know its good for them. January 2, 2014
