In general, kittens should eat kitten food until they are around 90 percent of their adult weight. At this point, they are at their full adult height and just have some final filling out to do.
- Most kittens reach this milestone at about 10 to 12 months of age, making this the ideal time to switch to adult cat food.
- An exception to this rule may apply to large breed cats. Larger breeds, like Maine Coons, don’t reach maturity until they are 18 months to 2 years of age. Keep feeding these big kitties kitten food until they are at least 18 months old.
Always speak with your veterinarian if you have any concerns about when to switch from kitten to adult cat food
