General information

Everything published on Pets in World — the calculators, the guides, the FAQ answers and the worked examples — is provided for general informational and educational purposes.

Our aim is to make one ordinary task easier. Working out roughly how much to feed a pet normally means reading a chart written for broad weight bands, doing arithmetic on your phone, and still feeling unsure. A well-built calculator handles that in a few seconds, and we think that is worth having.

What it cannot do is replace knowing your own animal, or replace professional advice where professional advice is what is needed. Those two things sit alongside each other comfortably; this page just makes the boundary clear.

The information here is offered in good faith and we work to keep it accurate and current. We publish the method behind every calculation openly, on the tool page itself, so you can see exactly how a number was produced rather than having to take our word for it.

Pet Food Calculator disclaimer

The reason is straightforward. The formulas behind the tool describe a typical animal of a given species and weight. Your pet is a specific animal, and a form on a web page can only see the few things you type into it.

These are some of the factors that genuinely affect how much a pet needs, and how they interact:

• Breed Metabolism and body composition vary between breeds, sometimes substantially even at the same weight.
• Age and life stage A growing animal is building tissue as well as running its metabolism, and needs are usually different again in later life.
• Activity level An animal that rests most of the day burns considerably less than one that works, runs or plays for long stretches.
• Body condition Two pets at the same weight can be in very different condition, and the appropriate amount differs accordingly.
• Health and reproductive status Illness, recovery, pregnancy, nursing and neuter status all change requirements in ways a calculator cannot model.
• Food formulation Calorie density varies enormously by product. The same daily energy need can mean very different portions on different foods.

Because of all this, the sensible way to use a result is as a reference point you monitor and adjust from, rather than a target to hit exactly.

No veterinary relationship

Pets in World is not a veterinary practice. We hold no veterinary or animal-nutrition qualifications and we do not claim any. Nothing on this site is veterinary advice, diagnosis or treatment, and using the site does not create a professional relationship of any kind between you and us.

This is not a limitation we are apologising for. It reflects a real difference: a veterinarian can examine your animal, take a history, run tests and see things that no website can. That is a different kind of help from what we offer, and for some questions it is the only kind that will do.

Please take the following to a qualified veterinarian:

• Any illness, injury, symptom or change in your pet’s condition.
• Medication, supplements, prescription diets or therapeutic feeding.
• Planned weight loss or weight gain programmes.
• Pregnancy, nursing, or recovery from illness or surgery.
• Weight changing without a deliberate change to feeding.
• Loss of appetite, refusing food, or a sudden change in eating habits.
• Feeding a very young, very old or unwell animal.

Please do not delay seeking professional help, or set aside advice a veterinarian has already given you, because of something you read here. If something looks urgent, contact a veterinarian straight away rather than researching first.

Accuracy of calculations

We take accuracy seriously. The formulas are drawn from established feeding equations, the arithmetic is tested, and the full method is published on each tool page so it can be checked by anyone who wants to.

Even so, some honest limits are worth stating:

• Estimates carry uncertainty by nature. Published formulas are built on population averages, so an individual animal may need meaningfully more or less than the calculated figure.
• Accuracy varies by species. Dogs and cats use a well-established resting-energy equation. Rabbits, birds and small rodents use simplified species-specific estimates, and the tool labels those results as rough on the page itself. Applying the dog and cat equation to them would produce a confident-looking number that means very little, so we do not.
• Your inputs drive the output. A wrong weight, the wrong unit, or a calorie figure from the wrong product will produce a wrong result, and the calculator has no way to know.
• Understanding develops. Nutritional guidance changes over time, and content that was accurate when written may not stay so indefinitely.

We do not warrant that the site is free of errors or that every figure is complete and current at all times. What we do commit to is fixing what we find and what you tell us about.

User responsibility

You know your pet and we do not, so decisions about their care sensibly remain with you. In practice that means a few simple habits, none of them onerous:

• Check what you enter. Confirm the weight, the unit and the calorie figure on your own packaging before relying on a result.
• Read the food label too. It is specific to the product you are actually feeding.
• Ask whether the result makes sense for your animal, and seek professional advice where it matters.
• Keep monitoring. Weigh your pet regularly and watch their body condition rather than assuming a figure stays correct indefinitely.
• Change amounts gradually. If an estimate differs a lot from current feeding, move towards it over several days rather than in one step.
• Follow veterinary guidance where you have it. It is based on your actual animal and takes precedence over any general estimate.

By using this site you accept that any decision you make about your pet’s feeding is your own, taken with whatever professional advice you consider appropriate. That is not a technicality — it is simply where the judgement genuinely sits.

External links

This site may link to other websites where they are genuinely useful. Those sites are run by other people, and we have no control over their content, their accuracy, or how they handle your information.

A link is not an endorsement, and it is not a statement that we have verified everything on the other side of it. When you follow one, you leave Pets in World and this disclaimer stops applying, so it is worth reading the policies of any site you land on.

The same caution applies to feeding advice you find elsewhere. There is a great deal of confident, contradictory information about pet nutrition online, much of it published by people with something to sell. Where an outside source conflicts with your food label or with your veterinarian, the label and the veterinarian are the better guides.

If a link on this site is broken or goes somewhere unexpected, please let us know so we can fix or remove it.
