Happy Healthy Cat! Our cat, Hailey has been eating Hills Science Diet dry cat food since we got her at the age of 2. She has thrived on it and has never once turned her nose at it. Noticing that as she got older she found it hard to chew the larger kibbles we decided to try the Mature 11+ food. The kibbles were smaller and easier for her to chew and it also gave her an unexpected dash of energy. She likes to run and play just like she did in her earlier years. She is now 13 and is still a joy to have around. Thank you Hills Science Diet for making a wonderful product that keeps out pets healthy and happy. November 22, 2013
This product has helped my cat live for 22 years! My cat, Dixie, is 22 years old this year. I have attributed her longevity to Hill's Science Diet Senior 11+ Indoor Age Defying Cat Food. Thanks for providing my cat and other cats and dogs out there with such wonderful cat food, Hill's Pet Foods! Keep up the good work, and always continue to make the good products that you do!

Ideal product for my 13 year old indoor cat Sadie I recently switched my senior cat's food from Optimal Care to Senior 11+ Indoor Age Defying to make sure she is getting the right nutrition for her age. The kibble size is great and she really likes it. October 6, 2013
They like it. It agrees with them. They like it. They eat it. They don't get sick on it. They are happy with it. That 's what matters. April 21, 2014
Nice to know there is an age/lifestyle diet for cats. My two kitties, ages 13 and 11 have been on this product for two months and had no trouble switching from the mature adult to this more specific food. They seem quite satisfied with the flavor and their fur and teeth and eyes all seem very healthy. April 14, 2014
Complete nutrition for the mature stages of life. One of the very few dry cat foods my cats will eat that also provides balanced nutrition needed for the mature adult cat. They enjoy the taste and texture as evidenced by their eagerness to eat the food before I have even finished distributing it! April 12, 2014
Concern... Good product but price continues to rise and weight declines. February 13, 2014
My cats enjoyed eating Sience Diet dry food I had a high value coupon so I purchased a bag of senior dry cat food. The price after the coupon was what I usually pay for the brand I get most often. While my cats did enjoy it and I believe it is good quality, I don't think I can continue buying it due to the cost. February 11, 2014
