My cat (a neutered male 6 years) took first food of "Royal Canin baby cat", and sterilization is passed to the "Royal Canin Vet Care Nutrition Neutered Cat Young Male", which I was required by my veto and I must say that my cat is in divinely doing well. The 10 kg bag lasts me 6 months, I keep it in an airtight bucket that was given me by Royal Canin (unfortunately no longer in it provides) and croquettes remains perfect, like new. The value is really interesting, I recommend purchasing these croquettes.
