Understanding Pet Feeding Amounts
A practical guide to portion sizes for cats and dogs
Daily calorie needs
Pets need a certain number of calories per day based on their size, age, and activity. Feeding calculators use formulas (such as RER and MER) to estimate these needs so you can match them with the right amount of food.
Food type matters
Wet food, dry kibble, and raw diets have different calorie densities. Our calculators let you enter your food's calories per cup or per gram so the recommended portions match what you actually feed.
Life stage and activity
Puppies and kittens need more calories per pound than adults; seniors often need fewer. Active pets need more than sedentary ones. The calculators account for these factors to give you tailored recommendations.

What you need to know about feeding portions
Daily calorie requirements
Learn how resting and maintenance energy requirements (RER/MER) are used to estimate how many calories your pet needs per day, and how that translates into portion sizes.
Using your food's label
Feeding calculators need your food's calorie content (per cup or per 100 g). We show you where to find this on the label and how to enter it for accurate results.
Adjusting for weight goals
If your pet needs to gain or lose weight, you can adjust the recommended portions. For safe weight loss or gain, your veterinarian can help you set a target and feeding plan.
Frequently Asked Questions About Pet Feeding
Common questions about how much to feed cats and dogs
Why use a pet feeding calculator?
Pet feeding calculators help you determine the right amount of food to give your cat or dog based on their weight, age, activity level, and the type of food you feed. They provide personalized daily portion recommendations so your pet gets the right calories without overfeeding or underfeeding.
How much should I feed my cat?
The amount depends on your cat's weight, age, activity level, and whether they are spayed/neutered. Use our Cat Feeding Calculator and enter your cat's details plus your food's calorie content. The calculator will recommend daily portions in cups or grams.
How much should I feed my dog?
Dogs need different amounts based on weight, age, activity level, and life stage (puppy, adult, senior). Use our Dog Feeding Calculator and input your dog's details and your food's calorie density. You'll get daily feeding recommendations tailored to your dog.
What is calorie density and why does it matter?
Calorie density is the number of calories per cup or per gram of food. Different foods vary widely—wet food, dry kibble, and raw diets have different densities. Feeding calculators use this so you get the correct volume (cups or grams) for your specific product.
How often should I feed my pet?
The calculator gives you a total daily amount. You can split it into two meals (morning and evening) for most adult dogs and cats. Puppies and kittens often need three or more meals per day. Divide the daily total by the number of meals you offer.
Should I consult a veterinarian about feeding amounts?
Yes. Our calculators provide estimates based on typical needs. If your pet has health conditions, is very active, or you're unsure, your veterinarian can recommend a feeding plan and confirm that the calculated portions are right for your pet.
