Why the bag's chart may say something else

Feeding charts on bags are written for an average cat and often assume more activity than a typical indoor pet gets. Use the table as a starting point, weigh your cat every 2 to 4 weeks, and change the amount by about 10% if the weight moves. Intact, very active or working cats need more; cats that gain weight easily need less.

Switching between two foods of the same brand can change calories a lot. Always recalculate the cups when you change food, and mix the new food in over 7 to 10 days.

Your own cat's weight, age and activity are in the calculator below: pick the food in the "find your food" box and it fills in the calories. All brands side by side: cat food calories per cup chart.
