ROYAL CANIN Indoor 27 is specially formulated with the nutritional needs of your adult indoor cat in mind.  

ROYAL CANIN Indoor 27 contains a highly digestible protein L.I.P. that’s specifically selected for its very high digestibility. This protein also helps to reduce the quantity of your cat’s stool, as well as reducing the smelly stool odour that occurs when cats have a lower intestinal transit due to a lack of exercise.   Your indoor cat’s activity levels are less than that of an outdoor cat,

ROYAL CANIN Indoor 27 food has a moderate fat content in order to ensure that your cat’s calorie intake is aligned with its level of activity – the calorie content also contributes to the maintenance of a healthy weight.   It’s common for indoor cats to spend long periods of time grooming themselves. Thanks to the inclusion of specific dietary fibres, such as psyllium, this food also helps to stimulate the clearance of ingested hair – resulting in a significantly reduced amount of hairballs.    What’s more, ROYAL CANIN Indoor 27 food also contributes to the health and maintenance of your adult cat’s urinary system.   : Indoor Appetite Control, Indoor Long Hair, and Indoor 7+.

Shiny fur Iza.w on 20 January 2021

I have 2 indoor domestic shorthairs. They have been on this food for about a year now and they both love it, though one of them was never that much into dry food. I have to use a slow feeder so they don't wolf it down. The biscuits are quite large so they do tend to leave a lot of crumbs around the bowl which is a little bit of a waste, I guess? They have very very shiny and soft fur even more now and the poop smells next to nothing so they're happy and I'm happy!
