Here's a handy chart to help you calculate approximate portion sizes based on overall package weight. Please remember that all amounts are estimations. This chart is also available for dogs.
Need to figure out how much food you need for one month?
To calculate the approximate amount of food you'd need in one month:
Find the number of cups (or patties) in the bag in the chart below. Then, divide the number of cups in the bag by the number of cups your cat will eat daily to determine the number of days of food in the bag.
Example:
If the chart indicates a bag has 32 cups, and your cat eats 1.5 cups per day, then 32 cups divided by 1.5 equals 21 days of food. Using this example, your cat would need at least two bags to have enough food for one month.
