Portion size depends on your cat's weight, age, activity level, and whether they're spayed or neutered, since all of these affect calorie needs. The most accurate starting point is the feeding chart on your cat’s food packaging, since calorie density varies by recipe and format. For wet food, portions are typically larger by volume since it has more moisture, while dry food is more calorie-dense per ounce.

Most adult cats do well with two meals a day, though this can vary based on weight, activity level, and whether you're feeding wet, dry, or a mix of both. Consistent feeding times also support steady digestion and make it easier to notice changes in appetite or routine over time.

"Nutritionally complete" means a food meets all of a cat's essential nutrient needs on its own, based on AAFCO standards, without needing to be paired with anything else.

This is different from "complementary" foods, like treats or toppers, which are meant to be fed alongside a complete diet, not as a cat's primary source of nutrition. That distinction matters because feeding only complementary foods long-term can leave nutritional gaps.

AAFCO (the Association of American Feed Control Officials) sets the nutritional standards pet food must meet to be labeled complete and balanced. Look for an AAFCO statement on the package, usually near the ingredient list or guaranteed analysis, confirming the food meets those standards for your cat's life stage. This matters because it's your assurance the food provides complete nutrition, not just good ingredients.

Outdoor cats typically burn more calories than indoor cats, since they're more active exploring, climbing, and hunting. Indoor cats, with less natural activity, generally need fewer calories to maintain a healthy weight.

Because exact needs vary by individual cat, the best approach is to start with your food's feeding guidelines, then adjust the portion up or down based on your cat's actual activity level and body condition over time.
