When a kitten is over 15 months old, it can start eating adult cat food. It's recommended to choose well-known, reputable brands to avoid buying inferior products that could harm your kitten's health. Additionally, it's recommended to choose cat food with a higher protein content, as this is beneficial for your kitten's health, as excessive carbohydrates can increase digestive stress. Finally, adult cats should also be regularly dewormed (both internally and externally) and vaccinated.
