Pro Plan Cat Aftercare 3kg has optimised nutrition for neutered or sterilised cats and is designed especially to keep your cat's kidneys healthy as their urinary system is one of their key protective systems. Some cats especially older ones may experience some form of kidney problems which can in some cases lead to a build up of waste and therefore dangerously high levels of toxins. Pro Plan Aftercare 3kg was developed by nutrition experts and vets to ensure it effectively supports your cat?s kidney function with a controlled PH formula which helps to maintain your neutered cat?s kidney health. Pro Plan Cat Aftercare 3kg is made from 2 fish protein sources for optimal palatability and is proven to reduce voluntary daily energy intake by 10%. The insoluble fibre and high protein ingredients help reduce the risk of excess fat deposition so it is extremely beneficial to overweight cats. It is also proven to help you cat?s teeth and gums by reducing tartar build up.
