Cats are easy to overfeed, and because they are small, even a little extra each day adds up quickly. Getting portions right is one of the most important things you can do for your cat's health.
Start with the feeding guide on your cat's food, which bases amounts on body weight. Treat these as a starting point rather than an exact rule, since activity level and metabolism vary from cat to cat.
Many cats do well with measured meals two or three times a day rather than a constantly full bowl. This makes it easier to notice changes in appetite and to keep weight in check. A simple kitchen scale or measuring cup brings useful precision.
Wet food has high moisture content, which supports hydration and urinary health, while dry food is convenient and can be used in puzzle feeders for enrichment. Many owners feed a combination of both.
Keep fresh water available at all times, and remember that treats count toward daily calories. If your cat is gaining or losing weight, or begging constantly, your veterinarian can help you adjust the plan.
