Get precise daily feeding amounts based on veterinary formulas. Just enter your pet's details below.
We use the standard veterinary formula: RER = 70 × (weight in kg)0.75 (Resting Energy Requirement). This is then multiplied by a factor based on your pet's age, neuter status, activity level, and body condition to get the Daily Energy Requirement (DER). These formulas are published by the National Research Council (NRC) and American Academy of Veterinary Nutrition.
This calculator provides a scientific estimate based on established veterinary formulas. Individual needs can vary by ±20% depending on metabolism, breed, environment, and overall health. Always monitor your pet's weight and body condition, and adjust portions as needed. For medical concerns, consult your veterinarian.
Puppies (under 6 months): 3–4 meals daily. Puppies (6–12 months): 2–3 meals. Adult dogs: 2 meals daily is ideal (prevents bloat in large breeds). Kittens: 3–4 meals. Adult cats: 2–3 meals. Dividing daily portions into multiple meals helps with digestion and satiety.
Both have benefits. Dry food is convenient, affordable, and helps with dental health. Wet food has higher moisture content (important for cats and dogs prone to UTIs) and is often more palatable. Combination feeding gives you the best of both worlds. Our calculator supports all three options.
Select the appropriate body condition in our calculator. For weight loss, we apply a reduced multiplier to create a safe calorie deficit. For weight gain, we increase the multiplier. In either case, transition gradually and monitor your pet's weight weekly. Always involve your vet in significant dietary changes.
RER (Resting Energy Requirement) is the number of calories your pet needs at complete rest — essentially the energy for basic bodily functions like breathing and digestion. DER (Daily Energy Requirement) is RER adjusted for your pet's specific lifestyle factors (neuter status, activity, life stage). This is the actual number you should feed to.
