Neutering a cat alters their metabolism, meaning that their general energy requirements are lower. That's why we've developed PRO PLAN® STERILISED with OPTIRENAL®, a food that's been specially formulated for their needs. Our OPTIRENAL® adult cat food formula is a scientifically designed combination of ingredients that promote good health and keep your cat supported. Adult cats can often suffer kidney problems as they age, so it's important to feed them a diet that's been specially formulated for them in their adult years. Kidney problems can occur for a number of reasons, but ensuring your cat is fed the right food can help prevent further renal problems. Our delicious recipe is rich in salmon and packed with ingredients for your cat to enjoy. It also has a reduced fat content of 12% to promote a healthy body weight in neutered cats, with controlled urinary pH levels help reduce the risk of urinary stones.

Our recipe includes amino acids, essential fatty acids and antioxidants to provide your adult cat with everything they need for a happy, healthy and active life. With a formula that's packed with essential nutrients, PRO PLAN® ADULT with OPTIRENAL® promotes healthy kidneys and ensures your cat's skin and coat is healthy and nourished.

If you are switching your cat to PRO PLAN® from another food (even a complete dry food that seems quite similar!), you will need to phase the 'old' food out over a period of 10 days, whilst introducing PRO PLAN® in increasing amounts. Don't forget to provide fresh water at all times.

PRO PLAN® is a complete and balanced cat food which provides excellent nutrition with scientifically proven benefits for cats. We understand that your cat is precious, and feeding her the right diet is an important part of taking care of her. Because your cat's needs will change throughout their life, PRO PLAN® provides a range of excellent nutrition at each life-stage: junior/kitten, adult and senior/7+.
