I switched to this cat food from Purina One mature formulation. Chicken is the first ingredient! Many other cat foods have rice or chicken by-products as the first ingredient. This food is specially formulated for the older, indoor cat. The other good thing about this food is that it is low in protein (27%), which is important for older cats because of decreased renal function; Purina One mature formualtion has too much protein (37%). My cat really likes the taste and he had no problem switching to this foo..
I adopted a mature stray this year. He was a great cat, but scruffy, and his bowel movements were absolutely toxic. I was feeding him Purina One, but on the vet's recommendation we switched to Royal Canin, and the difference in the cat is amazing. His coat is thick and soft, he no longer sheds, his dandruff is gone, and we don't need gas masks to clean his litter box. I would never have believed that a change in food could make so much difference, but it did. Great stuff.
My cats love this cat food! It is so much easier for them to eat as it is so much easier for them to chew. I have older cats and this is so much better for them. I can't get the larger bags of food at the local feed stores, so I order from Amazon, as I have 3 cats.
