Question 1

How is pet daily calorie intake calculated?

Accepted Answer

Pet calorie intake is calculated using the Resting Energy Requirement (RER) formula: 70 * (weight in kg ^ 0.75). This baseline is then adjusted with a lifestyle multiplier based on activity level, age, and neutering status.

Question 2

What is RER in pet nutrition?

Accepted Answer

RER stands for Resting Energy Requirement. It represents the energy expended by a pet at rest in a thermoneutral environment, which is the minimum energy needed for basic body functions like breathing and digestion.

Question 3

Why does my dog/cat need fewer/more calories?

Accepted Answer

Calorie needs vary based on metabolic rate, age, activity level, and health status. Working dogs or growing puppies/kittens need more energy, while sedentary or senior pets require fewer calories to maintain a healthy weight.

Question 4

Is this calculator suitable for puppies/kittens/senior pets?

Accepted Answer

Yes, our calculator includes multipliers for growth stages (puppies and kittens) and senior pets, adjusting the caloric intake to account for higher energy needs during growth or decreased metabolism in older age.

Question 5

Should I adjust calories for neutered pets?

Accepted Answer

Yes. Neutering or spaying can lower a pet's metabolic rate. Generally, neutered pets require about 20-30% fewer calories than intact pets of the same weight and activity level to prevent weight gain.
