When is it time to switch my growing kitten to adult cat food?

Updated On September 23rd, 2025

Pet's info: Cat | Maine Coon | Male | neutered | 7 months and 18 days old | 11.2 lbs

Figuring out food for my kitten? Rousseau is a 7 1/2 month old half mainecoon, and he is in great shape. He weighs 10.5 pounds. How long should we continue feeding him kitten food? He still seems to be growing a lot, he looks bigger all the time and he gains about a half pound a week on average. I feed him wet and dry kitten food, but he hates dry kitten food and will try to steal the dry adult food instead. We also give him freeze dried liver treats pretty regularily.

He is beautiful! He should be getting kitten food until at least 12-18 months. Kitten food has a different calcium and protein content than adult cat food that is important for proper skeletal development and growth. You could try a different brand if he no longer seems interested in the kitten food - be sure to make a slow transition from one food to the next.
