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+.
