Royal Canin Indoor Cat Formula Dry food is spectacular and you know that you are giving the cat the best they deserve. It is quite pricey, but if you have the money or want to give it to them every once in awhile its great too. Royal Canin has the best ingredients and their food is specific to each pet. This one is great for indoor cats and helps to keep hairballs to a minimum. It keeps their fur healthy, smooth and shiny. It is also softer on their digestive system and the ingredients are healthier than other foods, hence the higher price. My Persian cat loves the flavor and she is very picky. So when I find something she likes I add it to the list. A small amount goes a long way too and you usually don't need to give them as much as with other foods. This one is more filling. Quality of Ingredients The best! Flavor Selection My cat loves the flavor and she is a really picky eater. She is excited as soon as she smells this cat food and comes running to dig in.
