Wow.. OK I guess I never read the information on the bag... So diamond naturals has three different cat foods.. Indoor,active and kitten... The indoor is what I have been feeding my 6± yr old it says in stages adult but the active says adult,all stages... So I can just switch to active till my kitten is a year old and then switch back to indoor... GU es I should read label better...
