Important information about how to use the content and calculators on this website.

Last updated: May 2026

Cat Calculators is not a veterinary practice. Nothing on this website constitutes veterinary advice, diagnosis, or treatment. The calculators and content are for general educational and informational purposes only. Always consult a qualified, licensed veterinarian for advice specific to your cat’s health, diet, and medical needs.

General Information Disclaimer

The information provided on catcalculators.com is intended for general informational and educational purposes only. While we work hard to ensure the accuracy of our content and base our calculators on published veterinary guidelines, we make no warranties or representations regarding the completeness, accuracy, reliability, suitability, or availability of any information, calculator results, or related content on this site.

Cat care and feline health is a complex field. Individual cats vary enormously in their needs based on health status, genetics, breed, age, and many other factors. A calculator result that is appropriate for one cat may not be appropriate for another, even of the same weight and breed.

Not a Substitute for Veterinary Advice

The calculators, charts, and written content on this site are tools to help cat owners understand general principles and starting points. They are not intended to replace professional veterinary assessment.

You should always consult a licensed veterinarian before:

  • Making significant changes to your cat’s diet or calorie intake
  • Starting a weight loss programme for an overweight cat
  • Adjusting medication dosages (our medication calculators provide reference information only — always confirm with your vet)
  • Acting on any health concern, including unexplained weight changes, drinking changes, or behavioural changes
  • Making decisions about your cat’s reproductive health

If your cat is unwell, showing signs of distress, or you have any health concern about them, contact your veterinarian directly rather than consulting a website.

Calculator Accuracy and Limitations

Our calculators use established veterinary formulas such as the RER (Resting Energy Requirement) formula and WSAVA Body Condition Score standards. These are the same methodologies used in clinical veterinary nutrition practice. However, all formulas have limitations:

  • Individual variation: Studies show that individual cats can vary by up to 30% from formula predictions. A calculated daily calorie requirement is a starting point, not a prescription.
  • Formula assumptions: Calculators assume average food moisture content and standard body composition. Results may be less accurate for cats with unusual body composition or health conditions.
  • Measurement accuracy: Calculator results are only as good as the inputs provided. Inaccurate weight measurements will produce inaccurate results.
  • Medication calculators: Our medication dosage calculators (Benadryl, Methimazole, Gabapentin, etc.) provide reference information based on published veterinary dosing guidelines. Actual dosing for your specific cat must be determined by a veterinarian who has examined the animal and reviewed their full health history.
