These guideline amounts are a starting point and your cat may need more food depending upon age, activity, and temperament. In order to reach optimal body condition, you may need to adjust food intake. This represents the total recommended volume of food per day. You should divide the total recommended feeding amount by the number of times you feed your cat per day to get the actual portion size per feeding.


If you have a kitten, pregnant or nursing cat, we recommend feeding IAMS ProActive Health Kitten Food™.

Remember to have clean, fresh water available for your cat at all times.

Because IAMS ProActive Health Mature Adult Hairball Care Cat Food is complete and balanced for Maintenance, you do not need to add vitamin or mineral supplements.
