Pet Food Calculator

It depends on your dog's weight, age, activity level, and whether they're neutered. Our calculator uses the NRC formula: RER = 70 × (weight in kg)^0.75, then applies a multiplier based on life stage and body condition. For example, a neutered adult 25 kg dog needs roughly 1,100 kcal/day — about 3 cups of dry food. Always check the feeding guide on your specific food bag too.

An adult neutered cat needs about 1.2 × RER. For a 4 kg cat, that's roughly 230–260 kcal/day — about ⅔ cup of dry food or 1–1.5 cans of wet food. Kittens need 2–3× RER for growth. Adjust based on your cat's body condition and your vet's advice.

Both have pros and cons. Dry food is more calorie-dense (~350 kcal/cup for dogs), convenient, and good for dental health. Wet food (~250 kcal/can) provides hydration and is often more palatable. Many owners feed a mix. Our calculator shows amounts for both so you can decide. Browse dry dog food →

Adult dogs do well on 2 meals per day. Puppies under 6 months need 3–4 smaller meals. Cats typically prefer 2–3 meals per day. Free-feeding (leaving food out) works for some cats but can lead to obesity. Our calculator shows recommended meal frequency based on your pet's age.
