When is a good time to transition cats from kitten food to adult food?

Kitten food is specially formulated for kittens to achieve proper growth and development, and as such, is higher in calories than adult cat foods. Kittens should be fed kitten foods until they reach about 90% of their adult size, which typically occurs around 10-12 months of age. Any time a diet change is made, it should be done so gradually to minimize the risk of developing an upset stomach with vomiting and/or diarrhea. Transition the kitten food and adult food by mixing the foods together over 5-7 days, beginning with 75% old food and 25% new food for a day or two, then 50% old food and 50% new food, and then 25% old food with 75% new food.
