What is the RER for a cat?

Table of Contents

The equation for RER is the same for both cats and dogs. It is used to estimate the daily energy needed to sustain essential bodily functions (e.g. respiration, circulation, digestion, metabolism) while the dog/cat is at rest in a thermoneutral environment.

How do you calculate cat RER?

30 x (body weight in kilograms) + 70 x3d RER for medium-sized patients. So if Spot weighs 44 pounds (or 20 kg), the equation would look like:
70 x body weight in kilograms to the xbe power x3d RER for small/large patients.

How is RER vet calculated?

(Resting Energy Requirements or RER), which can be calculated by multiplying the animal’s body weight in kilograms raised to the xbe power by 70, for example, a 10kg (22lb) adult neutered dog of healthy weight needs RER x3d 70(10kg)3/4 u2248 400 Calories/day.

What is RER in veterinary medicine?

RER – Resting Energy Requirement represents the energy requirement for a normal animal at rest in a thermoneutral environment, and is based on body weight.

How do you calculate kcal for a cat?

Rule-of-Thumb Cat Calorie Calculator A rule-of-thumb for calorie requirements for a normal adult cat is 20 to 33 calories per pound depending on their energy level. A 10-pound indoor cat should eat about 200 calories and an outdoor active cat can eat about 330 calories per day.

What is RER for cats?

Resting energy requirement (RER) is a function of metabolic body size. Energy expenditure is related to surface area, and body surface area decreases as body weight increases. The equation for RER is the same for both cats and dogs.

How do you calculate kitten RER?

Calculate the perfect portions for pets

30 x (body weight in kilograms) + 70 x3d RER for medium-sized patients. So if Spot weighs 44 pounds (or 20 kg), the equation would look like:
70 x body weight in kilograms to the xbe power x3d RER for small/large patients.

How do you calculate cat Kcals?

For example, to estimate the RER or resting energy requirements, for an adult neutered cat you use the following formula RER x3d 70 x (ideal weight in kilograms) 3/4. You then multiply this times 1.2, which is the appropriate multiplier for a neutered cat. However, this calorie count should only be viewed as an estimate.

What is the difference between RER and Mer?

RER – Resting Energy Requirement represents the energy requirement for a normal animal at rest in a thermoneutral environment, and is based on body weight.

What is the use of RER in animals?

How do you calculate maintenance energy requirement?

RER is a function of metabolic body size and represents the energy requirement of the patient while at rest at a controlled temperature. Spot’s RER is thus 670 kcal per day. For example, if Tiny weighs 3 pounds (or 1.36 kg) and we use the formula for medium-sized dogs, Tiny’s RER calculates to 111 kcal per day.

What is metabolic energy requirement?

Calories

Resting Energy Requirement (RER) x3d 70 (body weight in kg)^0.75.
Maintenance Energy Requirement (MER) x3d appropriate multiplier x RER.

How do you calculate energy in animals?

RER – Resting Energy Requirement represents the energy requirement for a normal animal at rest in a thermoneutral environment, and is based on body weight.

How do you calculate how much food an animal needs?

How do you calculate cat food needs?

Whatever you decide, simply divide the number of cans you need to feed in a day by the number of meals you want to provide, and you’ll have the right portion for each meal. If you’re watching your cat’s weight, you’ll also need to subtract the calories provided by any treats you give as well as any dry food you offer.
