Cat Food & Daily Calorie Calculator

Plan the calories. Measure the portions. Keep every meal balanced.

Your Cat’s Profile

Current weight

Life stage

Activity factor

Body Condition Score (BCS)

Illustrative top view

Body condition score, 1 to 95 / 9 · Ideal range

Feel the ribs, assess the waist. BCS needs hands-on assessment.

Target weight & special life stages

Weight loss uses a veterinarian-agreed target weight. Pregnancy/lactation need an individual plan.

Use a veterinarian-set daily calorie target

A BCS selection does not automatically change the factor or estimate an ideal weight. Consult your veterinary team for illness or unexplained weight change.

Wet food (30% of food calories)

64 g wet food≈ 0.75 cans

Illustrative portions — weigh the food; bowls are not measuring devices.

Per Meal · 2 meals / day

Equal food portions; treat calories are reserved separately. Meal timing should suit your cat’s needs.

Treats are part of the daily budget, not extra. Percentages above are shares of total daily energy.

Monitor & adjust

Track weight, body condition and appetite. Review the plan with your veterinary team.

A Closer Look at Body Condition

Lean · BCS 1–3

Ribs or bony landmarks may be prominent.
Arrange a nutritional assessment.

Ideal · BCS 4–5

Ribs are easy to feel, without excess covering.
A waist is visible behind the ribs.

Above ideal · BCS 6–9

Ribs may be harder to feel under fat.
Waist definition may be lost; abdominal fat may increase.

Illustrative guide, not a diagnostic chart. Muscle condition is a separate assessment.

Calculation & assumptions

RER = 70 × weight(kg)^0.75

Daily energy = RER × selected factor, or your veterinarian-set target

Food budget = daily energy − treats

Example (this estimate)

Food split is based on calories, not grams or volume. Portions are rounded for display; the report preserves calculation precision.

Life-stage factors & limitations

Starting scenarios: neutered adult 1.2, intact adult 1.4, inactive adult 1.0 and growing kitten 2.5. An active-adult 1.4 scenario is adjustable. Weight loss uses 0.8 × RER at a veterinarian-agreed target weight. Pregnancy and lactation require a veterinary calorie target here. These are estimates, not fixed prescriptions. Never fast a cat or make abrupt calorie restrictions for weight loss.

Frequently asked questions

How do I use the food label?

Find the metabolizable calorie content per cup, can, 100 g or kilogram. Cup and can gram equivalents require the weight of that product’s cup or can; no universal cup-to-gram conversion is used. Changing a calorie unit preserves the density when the necessary weight is supplied.

Can I mix dry and wet food?

Yes, if both suit your cat’s life stage and any medical needs. Allocate their shares of the complete-food calorie budget after treats. Mixing by calorie percentage does not mean the same percentage by weight. Ask your veterinarian about therapeutic diets.

How often should I reassess portions?

Track weight, body condition and appetite and review the plan with your veterinary team. Needs change with growth, activity, neutering and health. A food change or weight-management plan needs follow-up rather than relying on one calculation.
