I recently bought this product for Stripes. She enjoyed it! She is 12 years old so I chose the Healthy Aging Formula. My family noticed she felt softer, there's a possibility could be from the food. She also has a sensitive stomach and often doesn't keep down new food. This kind went over well. I only bought can, at a reasonable price, so I'm sure if the use of this brand was constant it would be more beneficial. I also used the wet food to mix in a vitamin, which worked fairly well. I did some research on the company because I made a review video. The company is well back with professional veterinarians and scientists working on their formulas, so I believe the brand to be very trustworthy. Their website also has other pet health related content which could be very useful. I bought the product in a PetCo.
